Hello there ! I created my first one mod / map for my multiplayer server (PaxCruentus). The map includes only a big building ( an hospital). The building works proprely in solo mode but when it is loaded on the multiplayer, there are only the shadows which appear. Do you know why, can you help me please ? - -Sorry for the spelling mistakes- - [You have the link of the mod below + a screenshot] https://steamcommunity.com/sharedfiles/filedetails/?id=1447743657
