Opening generated chests, which got a loottable while having the luck potion effects applied creates an error in the logfile and no items are being generated in the chest.

The following error is present:

This might be an incompatibility but I'm not sure.

I believe what the problem is, just to be sure, which version did you use?

I Confirm the Bug, Chests are not generating Loottable content while having Luck Effect, I'll be Fixing the bug for the next Version, Thanks for the Feedback <3

I'm currently using AppleTreesRev-Forge-1.16.5-v2.1 on 1.16.5, my Forge version is 36.2.2.

What you loot was a dungeon Chest, buried treasure or something like that?
