Board Thread:LotR Mod Technical Support/@comment-28344925-20170724185516/@comment-25330335-20170724213620

My guess is that one of your other mods coremods something that LOTR is now trying to coremod and forge/java don't like it. Look through the log and see if one of your other mods is "Patching Methods" or something like that. Then try and remove that mod.
