I don't know what the forget is causing it for sure, but I think I've narrowed it down to Tool_NewDuplicator and Gamemode_Slayer
both of these enabled seem to be the cause of me crashing when attempting to host
Idk how to properly find it and its loving making my head hurt
Heres the console log, idk if thats needed but here it is anyway
