Observed behaviour

Server crashes when i try to open a chest from a ruined nether portal. i was playing on aternos (idk if that matters). i was playing with some other mods but irons spells n spellbooks is the only one that appears in the crash report. (sorry if this is written wrong it's the first time i ever write something like this)

Expected behaviour

the server doesn't crash and i can open the chest.

Steps to reproduce

1 create an aternos server
2 install other mods
3 find a ruined nether portal
4 try to open the chest

Server Type

Dedicated Server

I believe this is an issue with the latest version of forge

I cannot reproduce this on a regular server with these mods installed. It is likely an Aternos issue.

@Hubix0987 alternatively, do you have any datapacks that change the loot tables?

I have encountered the same sort of issue with my own (admittedly large) list of mods, I will investigate myself if I can reproduce the issue with a minimal list.

@karelmikie3 i also see another mod is mixing-in to the loot tables in your log. I'll reopen the issue. maybe there is something deeper here.

I have a few similar crashes

I haven't had time to test with fewer mods yet

fixed in latest version
