I've just imported my mission from one map to another and essentially did this by copy pasting all the map objects and icons onto the other maps. Initially I was having an issue with there being no roles, meaning that the units weren't set to playable which I fixed. Now when I join the map there is no slot that doesn't spawn a seagull. I'm assuming this has something to do with my mission.sqm however I've been at it for about 5 hours now and can't seem to figure it out. I can provide any information you require, these two lines may be useful:
Client RPT:
2:43:23 Attempt to override final function - bis_fnc_preload_server
2:43:26 creating seagull (no person)
Server RPT:
