Updated FML:
MinecraftForge/FML@591e65fa1aa52d2a72dc527ad1c2ac53c8eb94c4 Revert "Use the reobfuscation maps in the reflection helper for field lookups: should help some reflection cases with the deobf."
MinecraftForge/FML@2a779ec3289f695b477ec6b0822a27801e2deba1 Try a different way of remapping the fields. Should work because it's userspace, not relauncher space
MinecraftForge/FML@ca2d8bd83475f37946b86cf6fabd8ff810f9c2bf Fix reflection helper: it needs to unmap the classname to find the field maps.
