AEPatch2 is a Sponge plugin that uses Mixin to change the code of Applied Energistics 2 at runtime and patch some issues. At the moment, it just gives the AE2 Fake Player a name ([AE2] instead the generic [Minecraft]). I'll be using this to patch eventual issues later.
To run this, you must rename your AE2 jar file to ae2.jar, so this mod can patch it. It'll throw an error if the mod doesn't exist. Also, this plugin will only load if it's in the mods folder. AEPatch2 is built against AE2 rv6-stable-2, but it should work on earlier versions.
The compiled jar is in the releases section. Enjoy it!
