When I set the Entity module to false, it causes a crash while initializing the game: https://pastebin.com/5f9qpXsu Interestingly, the true/false status of other modules seems to affect whether or not the crash happens. For example: setting both the Tools and Entity modules to false will let the game run no problem; setting both the Overworld and Entity modules to false will result in a crash; setting the Overworld module to false and the Entity module to true causes no crash. I'm using Mantle 1.10.2-1.1.5, Natura 1.10.2-4.1.0.80, and Forge 12.18.3.2185 with no other mods installed and otherwise untouched config files.
