Having issues with Mods in multiplayer only. I load the same exact mods with no issue in single player. For some reason it always states that one mod can not be activated due to an incompatibility issue when me or a friend try to join our multiplayer game created by either one of us. We have the same exact mods loaded and have no issues with single player with same mods. The mods in question are Odinblade's series. We have them loading in correct order so this is not the issue. Even tried not loading this series and just loading a single mod the Heaphaistos's Berserker Class and got the same exact error, Any help would be great.
