When I enter a certain area in my world I get a crash that could be in Environmental. I have included the crash log
crash-2021-09-28_09.21.01-server.txt
.

Same issue:

log: https://pastebin.com/4G8y2E7D
Environmental 1.1.0
Minecraft 1.16.5
Forge 36.2.8

This is the first time I've gotten this crash and I can't guarantee it will happen again, nevermind reliably reproducing it. Hopefully this log helps diagnose the issue.

1.16 is not supported anymore, but looks an Apotheosis issue
