Updated to BTW CE 2.1.4!
Fourth test release, probably some bugs still left somewhere. Now with full mixin support, multiple addons tested. Works on Client and Server. Bytecode verifier has returned.
Just put this jar file into a 1.5.2 Fabric Minecraft/Server installation mods folder and launch, nothing extra needed.
Use Java 8!
Debug version prints all patched classes to the console, along with some other stuff. Take that one if you want to have a scope of the amount of things getting patched, debugging or want a giant log all the time. Else take the normal one.
