Minecraft version: 1.12.2 [change as necessary]
Wizardry version: 4.2.0 [change as necessary]
Environment: Singleplayer

Issue details: I was walking and loaded up a new chunk which caused my game to lag and then crash. From reading the report it could have been some sort of conflict between a potion effect in the mod and a dweller zombie entity in the quark mod?

Other mods involved: quark

Duplicate of #166. This was fixed in the 4.2.1 hotfix.
