On second thoughts its coming up with this a lot 'ModIdArgument@7ddcb30f'

Hi there,

I have removed and added some mods to my server today. Now when I try to play the auto save isnt working and every time i die or disconnect it deleted anything i've done.

Theese are the two messages im getting.

I am using forge mods on version 1.16.1. I think its a server issue not a mod issue but i dont know

[net.minecraft.world.server.ChunkManager/]: Failed to save chunk 63,-39 java.lang.NullPointerException: null

and

Hello Guys,

Could you please add the mod "More Materials"?

I think this mod is quite old however I am playing in 1.7.10! The mod has some super cool blocks for building houses and walls and roofs which I think would be really fun to play with.
