Minecraft version: 1.12.2
Wizardry version: 4.3.1 (I think) (Whatever the latest Roguelike Adventures and Dungeons modpack uses)
Environment: Singleplayer

Issue details: I was fighting some evil wizards and I had just killed them all and was going to the chest when the game crashed. I don't know why and I am now unable to get back on the server.

Other mods involved: Ancient Spellcaft by Dan.

Link to crash report (if applicable): I don't know if this is right sorry.
