Using /kill in spectator renders the player in a half dead half alive trance, when the chat is opened its permanently open and using /kill again does nothing, an error appears saying "An unexpected error occurred while attempting to use this command"

You literally have to force close the game and possibly loose progress, not to mention large modpacks have long load times

fixed in 2.0.0 re-write @UnlimatedStone9

Also using commands doesn't close chat nor even remove the command from the chat

/tp just jitters the player mentally too

I could maybe investigate when it happens. Is the player not in the world or isDead in the world on client side I could maybe set a boolean on client side. Even if it's a vanilla bug could maybe get fixed?

unable to reproduce on demand this is a vanilla bug which can actually happen without this mod it's just more common since you skip the respawn screen

oh ok then thanks jredfox!

the player basically just floats wherever they died, no matter the gamemode and teleporting them just makes them go jittery, I really don't know what is going on, commands like setblock and such don't work so I believe the player is considered as dead

I noticed relauching the save resulted in a crash

post said crash. sounds to me like a broken mod I manually call all forge events needed and do everything to respawn the player properly

If you want the crash report here it is
I believe this is the correct one

crash-2018-07-29_02.58.36-server.txt

Caused by: java.lang.ClassNotFoundException: com.EvilNotch.lib.minecraft.EntityUtil. class does in fact exist

Also try removing different coremods as they might be breaking forge asm

You have deleted a class and the jar is corrupt. Download the latest Evil Notch Lib

Oh ok then, Thanks jredfox!

If you don't crash anymore let me know and I will try and figure out what's going on here. Won't be immediate since it's a minor bug and the lib needs to be brought out of beta
