I can't speak to whatever may be in the pastebin (I don't have time at the moment to read it), but those two "errors" are both completely normal. FML just isn't bothering to exempt bits of itself from the checks.This might also be suspicious:
- [23:35:05] [Client thread/ERROR] [FML]: FML has detected a mod that is using a package name based on 'net.minecraft.src' : net.minecraft.src.FMLRenderAccessLibrary. This is generally a severe programming error. There should be no mod code in the minecraft namespace. MOVE YOUR MOD! If you're in eclipse, select your source code and 'refactor' it into a new package. Go on. DO IT NOW!
- [23:35:05] [Client thread/ERROR] [FML]: FML has detected a mod that is using a package name based on 'net.minecraft.src' : net.minecraft.src.Start. This is generally a severe programming error. There should be no mod code in the minecraft namespace. MOVE YOUR MOD! If you're in eclipse, select your source code and 'refactor' it into a new package. Go on. DO IT NOW!
