[1.16.5] Server crashes when new loot is generated in the chest

[FrezeON]

Minecraft Version : 1.16.5

Mohist Version : 958

Operating System : Ubuntu 20.04

Description of issue : The error says that most likely the problem is not in Mohist, but I did not find another place where they could help me with this problem.

When opening some chests in dungeons, when loot is generated in them, the server falls into an error and stops. In the log, I could not find what exactly breaks the server and how to fix it.

This bug did not appear in the latest update, it was also present in previous versions of Mohist.

Java version: openjdk 11.0.14.1 Start.sh while true; do java -Xms7G -Xmx9G -jar mohist.jar && break; done
