Don't know exactly how to describe the problem in a header. What happened:
I left the game when I was in the mining dimension. When loading the save game the other day then the game crashes just after the "100%" rectangle when the world should show up.
Other saves do work, it is just the one where I left in the mining dimension.

Fixed in 0ad2805. Thank you!

1.4.1: Not fixed jet. As before, other saves do work, just the one with the "quitting in mining dimension" kills the game with a crash.

I've tried everything and I can't reproduce this. I went from 1.3.1 to 1.4.0 to 1.4.1 in the same singleplayer world and I never got it to crash. If you just installed 1.4.1 this morning on the client there should be no issue-- I'm guessing it only crashes when the stars align from previously failing versions. I'm going to ask around and see if other people can reproduce it. I will get back to you shortly.

OK, thanks. If you need me to do any more testing I can. I have not tried this on a new world. I really don't want to start over.

Could you send me the world save file? Zip it up and attach it here.

Do you have somewhere else I can send it to? It wont let me attach anything bigger than 10 megs on here, with max compression its still 34megs, I guess I could split it up if you could put it back together.

The two options I can think of are dropbox or a git repo. Should be easy to just create a new repository on this site and upload the jar to it.

If I have the jar, I can attempt to reproduce the issue and also fix your save so your player just spawns in the overworld.

Try this link and see if this is what you need.

Yeah, that's definitely crashing. Thanks much.

I having the same issue, Just installed this mod this morning. My version Minecraft is 1.41.1 My version of the mod is 1.4.1

Are you on a server? Can you go into your saves folder and delete the Miner's Horizon world folder, as well as the config file (assuming it's from an older version and needs to be re-built) and then try to re-join?

I just started the game up in Fabric 1.14.1 with API 3 and tried the following things:

• logging in and out
• fully closing game and logging in an out
• deleting the dimension while I'm still in it and relogging

I did not crash. This was on a client, so it may be different on a server.

I know what the issue is but I'm not sure how to reproduce it reliably.

I'm not on a server, do you want me to delete "DIM_miners_horizon" folder in my world save folder?

Yeah. Also, delete the minershorizon.json file in your config folder.

After I deleted those two things.

Boredhermit & Knito, can you try this new version on the worlds that are crashing? It should put your character at world spawn (in the Overworld) and fix the NBT issues. Seems like this was a one-off thing that probably only hit the two of you, and maybe a couple of others at most.

Note that this is a zipped jar, so unzip it before adding it to your mods folder.
miners-horizon-1.4.2.zip

Thank you so much for fixing my save, it's works!!!!!! There is something I noticed,after I got back to my house from my spawn point,I slept in a bed, went to the miner dimension. I did "save and quit" when I reloaded it put back at the spot you reset my spawn...... I dont know if that was intentional or not, just thought you should know.

ugh, figured something like that would happen. Might be worth leaving the mining dimension, removing the Miner's Horizon jar & world file, re-loading into the world, (exiting) re-adding the jar, and re-joining back into the world. I haven't pushed this jar to CurseForge yet so I'll try to look for a solution to that as well.

Thank you for the test file. It does not crash but takes me back near my world spawn point in the overworld. The saved game is rescued!
Thank you very much for helping me with that. In the next days I will take care on leaving the game in the overworld only.
:)

Should be fully fixed in the 1.5.0 release (no more weird spawn mechanics, either).
