It's me again but this time with another issue that whenever I tried to put any "weapon" (except for the bow) in my offhand slot that the game crashes. I think it has somethin to do with another mod called Tons Of Enchants which what that mod does is it adds enchantments and one in particular seems to not play well with Epic Fight Mod that the game crashes. Anyways here's the crash report and log:

Crash Report: crash-2021-03-10_05.09.42-server.txt

Log: latest.log

Btw I've just looked into this log that I've provided to you and I see the mod Tons Of Enchantments in there with one of it's enchants that applies an attribute when an attribute that's possibly similar was already applied to the player somehow without me even having the enchantment on my items. So I'll go report this same issue to them but it would be about one of their enchantments conflicting with another mod. I originally thought that this issue was caused from a mod called Attribute Fix+ but the game crashed without it as the same error from before so it ain't Attribute Fix+ that's causing this.
Also;
Minecraft: 1.16.5
Forge: 36.0.46
Epic Fight Mod: 3.0.2
Tons of Enchants: 0.4 SERVER-FIX

I guess I have to update the developing environment to 1.16.5 forge. All crashes are occurred from registering Attributes. I'll notify you then.

Hey, could you try it in the 3.0.4 version? I updated the development environment, so I hope it would fix the problem.

I had downloaded version 3.0.3 but not 3.0.4 yet but after I'm finished with a different game called Block City Wars (later on today) before I start my modded minecraft play session then I'll grab 3.0.4 and see if it's fixed also the owner of Tons of Enchants wanted discord so that both him and I could discuss about the problem which may not be one of his enchantments (heart healthy).

I think I may know the main cause of the issue is. I have a mod called OffHandCombat which allows me to use anything that can deal entity damage (i.g. I can dual wield two netherite swords or axes with OffHandCombat) and Epic Fight Mod may be hard-coded to only allow us to use both vanilla and/or modded weapons in our main hand, especially when we're in combat mode. In the comments on Epic Fight Mod's curseforge page I had asked if this mod was compatible with Epic Fight Mod.
Well now we may know the answer now that both of these mods aren't compatible since I just did the same thing again but this time with Project Rankine's Invar Hammer and yes the game did crash again from the same crash as before. Again...
Tons Of Enchants has nothing to do with all of this mess and neither does Attribute Fix and Tiered.
So there really is a confliction between two mods, OffHandCombat and Epic FIght Mod.
Now that I may have discovered the main cause of this now I have three options;

1. I continue to play with both mods but I can no longer dual wield but there won't be any more crashes if I avoid putting any tool or weapon (except for the bow since I can't put the bow in the off-hand slot anyways since Epic Fight Mod prevents this) both vanilla or modded.
2. I remove Epic Fight Mod to allow dual wielding but I won't have Epic Fight Mod's custom combat system and the animations form the mod...
3. I remove OffHandCombat to have Epic Fight Mod's custom combat system and its awesome animations but there won't be any more dual wielding...
   Which one shall I do while I wait for a compatibility with both of these mods if possible?
   (Btw I'm gonna go back onto my modded world right now with both of the mods installed still since I just wanna play right now but without putting anything in the off-hand slot except for non-weapon type things like a torch since I have OptIfine's dynamic lighting enabled)

EDIT: I've just realized that when I saw the mod review for Epic Fight Mod I thought I saw someone dual wielding two swords.
So I'm gonna remove OffHandCombat and try to dual wield with Epic Fight Mod since I think I realize and understand the issue which apparently dual wielding is an attribute which OffHandCombat already applies this "attribute" to the player while Epic Fight Mod tries to do the very same thing but fails which in turn causes the game to throw a firing event exception and crashes whenever I put any type of weapon (I.g. a tool like a pickaxe or an axe as a weapon or a sword) in the off-hand slot.
So maybe you could try to make Epic Fight Mod compatible with OffHandCombat but only when OffHandCombat is installed.

UPDATE: So the game still crashes even after uninstalling OffHandCombat and even uninstalled Tons Of Enchants.
Epic Fight Mod is clearly not working with Project Rankine at all as of it's tools and weapons when in the off-hand slot.
This has lead me to believe that I'll have to uninstall Epic Fight Mod since I'm obviously not uninstalling Project Rankine cause my world is themed for Project Rankine.
If I uninstall Project Rankine in favor for Epic Fight Mod then the underground in the Overworld would be one MASSIVE, MASSIVE, MASSIVE cave with no stone except for very, very small patches of it here and there since Project Rankine messes with the Overworld's world generation by adding many different types of stone to the Overworld.
Project Rankine may also mess with the Nether's generation, and possibly the End's generation as well and could potentially cause the world to be corrupted.
So I have no choice to uninstall Epic Fight Mod for my current world so that the crashes would finally stop and I would be able to put anything in my off-hand slot again but for my next world I'll have Epic Fight Mod in it.
Also I may include it in my previous world before the one I'm playing on now.

Might this be related to issue #72? I am also having server issues and the latest version that works with my server right now is 3.0.2. Something past that versions must have been changed to cause such issues

same problem as #171 #72 and #288

Hey, Just checking in if these problems have been addressed and fixed already.
Still not gonna play with Epic Fight Mod till those issues are resolved but I do miss playing with EFM...
Also just looked through the issues tap on here and I see that there's a butt ton of problems with EFM which makes me not want to play with EFM even tho I don't play on *multiplayer....

*(Since I don't have any friends who plays java edition, also if the multiplayer server itself is located on the other side of the world that I'll get too far behind the server itself since my internet is garbage....)

Yes this issue may relate to yours and my recent world may have just died from this piece of code (maninhouse.epicfight.capabilities.entity.LivingData.initAttributes(LivingData.java:84) from Epic Fight Mod while playing with Nugget's Dungeons II mod.
Apparently Epic Fight Mod doesn't like playing with certain dungeon mods and mods like Project Rankine.
There's something definitely wrong with at piece of code and what does it do?
What is it responsible for and why doesn't it like other mods and certain dungeon mods??
I feel like I'm going to stop playing with Epic Fight Mod till this issue gets fixed cause it's starting to annoy me now and losing my most recent world to this problem is the last straw to be playing with this mod since a few pieces of it are clearly broken in some way.
Sure some people may manage to find a fix for this issue but I just don't have the time and patience to figure out how to fix this issue myself and it's not my responsibility to find a fix for this problem since it ain't my mod to do that in the first place.
So until this issue is fixed/removed I'm gonna either backport the mod version to a time when the mod was working properly (3.0.2 or prior to 3.0.2) or I completely stop playing with Epic Fight Mod...
Also this issue is happening on both the client (singleplayer) and server (multiplayer) since I was playing with Epic Fight Mod on singleplayer.
Now I'll have to create a new world since the last one died from this problem as a ticking world crash but this time without Epic Fight Mod installed.

One last thing, May I suggest allowing us to dual wield in battle mode? Since I have OffHandCombat mod installed that allows me to dual wield but while I'm not in combat mode and with Epic Fight Mod there's no animations for when wielding one-handed weapons in the off-hand.
So everything that I've said like possibly over a week ago is irrelevant cause Epic Fight Mod disables OffHandCombat mod when in combat mode.
Also don't go into 3rd person view when wielding two weapons with both hands with Epic Fight Mod since there's no custom animations for that...

Hi, does the latest version (3.1.1) finally fixes (maninhouse.epicfight.capabilities.entity.LivingData.initAttributes(LivingData.java:84)?
Or do I and many other people who has experienced issues with (maninhouse.epicfight.capabilities.entity.LivingData.initAttributes(LivingData.java:84) still has to wait till you find the solution to it?

Btw I'm not playing with Epic Fight Mod for my current world since I'm using firearms (Mr.Crayfish's Gun mod and A.V.A Alliance of Valiant Arms mod) and playing with Mine Colonies mod but maybe my next world would have this mod in it.
Also, I know that the 1.12 version is capable of having firearm animations for gun mods like the 1.12.2 version of Mr.Crayfish's Gun mod and Vic's Modern Warfare 2.0 Contagion but I don't really think that those animations were carried over to 1.16.5 with Mr.Crayfish's Gun mod for 1.16.5...
If they were carried over from 1.12.2 to 1.16.5 then I may reconsider adding Epic Fight Mod onto my current world while I'm using both Mr.Crayfish's Gun Mod and A.V.A Alliance of Valiant Arms on my travels to conquer the dungeons from When Dungeons Aries mod while I would be building my colony in Mine Colonies mod.

Same issue on 3.1.3. Still getting maninhouse.epicfight.capabilities.entity.LivingData.initAttributes(LivingData.java:82) ~[epicfight:1.0] {re:classloading}. The latest version that works for me is 3.0.2 @Yesssssman

I'm no longer playing with Epic Fight Mod cause I ran into another crash which was a weird one that I have Not Enough Crashes installed and instead of being put back to the title screen I was brought to the multiplayer server screen.
Btw "maninhouse.epicfight.capabilities.entity.LivingData.initAttributes(LivingData.java:82) ~[epicfight:1.0] {re:classloading" thats what was my last crash which is the very last straw for playing with this mod till @Yesssssman or the owner of this mod fixes this mod cause as I see it Epic Fight Mod is in a poor state cause of some of it's capabilities/attributes aren't functioning properly and are possibly broken/bugged!!! (btw I was in a desert biome when that crash started happening, thought that A.O.A aka Nevermine was the cause of the crash but it was obvious to which mod was really the cause of the crash, EPIC FIGHT!...)
All that needs to happen with these pieces of code is some major polishing/fixing then we shall see if I should return to Epic Fight Mod.
Btw I'm not dissing the mod or anything or even the creator of Epic Fight Mod but I'm just done and over with it's current issues/bugs.
So to stop encountering with Epic Fight's problems I'm just going to stop playing with the mod till these issues gets resolved once and for all and everyone who's playing with Epic Fight should do the same to keep all of us sane instead of all of us going insane if we all just keep playing with Epic Fight while it still has some major problems going on with it right now that's latterly hindering gameplay both vanilla and by this mod entirely to the point that the mod is unplayable.
