Server crash

[RageQuitAmy]

Ok so I help with a minecraft server and the server crashes quite a lot, usually because of a different mod but sometimes this one causes it. Here is a pastebin link for the crash, if it doesn't give enough information please let me know and I will try to give you more information :). Crash Report

Thanks in advance.

From my analysis the cause is Additional Events assuming BlockState#getDrops return is mutable and consequently passing that collection through into its DropLootEvent to be modified by event consumers, such as Random Enchantments. In vanilla code it is a typical case for an unmodifiable list to be returned such as for an empty loot table and modded blocks widen those cases.

I would new ArrayList wrap the return list on this line:
