I have tried recompiling, decompiling, updating mcp and forge and switching version several times. None have worked. Minecraft will run fine through the launcher and it's using the same version.
I am new to java and don't have much experience with it. I would guess the error is to do with LMZA files, but I don't know how to fix.
Thank you for reading answer as soon as possible because I'm going on holiday tomorrow.
