1. start mission that uses BIS_fnc_MP (on a dedicated server) with the same or similar things being used with it as in Stratis-RP:Ultimate
2.let it run for a while, maybe do some stuff like harvesting to make it a more legit test.
3.try to buy a car after a while and see if you get teleported to an island just north of Stratis. (if you do, then the function has been 'broken' and the whole mission is broke until the server is restarted)
