If you move this mod and any other map mod to load after Bobbert's Coop mod from Nexus, it should clear up the conflicts and be functional. We edited the mod.json in the mod's folder to change the default load order to 11. Bobbert's is 9, and we set MagnumForceGB's Lore map to 10.
Haven't tried simply using Nexus' mod loader, but I'd think it would work too. Only tested for 2 player coop.
