I am updating my pack, Conquest Colonies Arcane, though this version has not been published. Here is my development version Conquest Colonies Arcane 1.12.2-2.3.0.zip that is causing this issue.

Expected Behavior
The singleplayer world should not crash when exploring the world

Current Behavior
The singleplayer world crashes when exploring the world

Steps to Reproduce
Exploring by walking or using /rtp
The world will suddenly crash
Possible Solution

Conquest colonies arcane is an incompatible modpack - it uses OTG and Conquest Reforged, which are both unworkable with AW2
