So, I do indeed run like 20 mods when I play. Even when I narrow it down to 2 mods, It doesn't work. It's not a crash, it says game output. Here is what is says:

Core Mod? Ok, I think I know what plugin is causing the problem. Checking...

LOL, I was just being blind, 5zig was sitting in my mods folder xD Thanks for the help
