This campaign crashes when we leave the safe room in the map CityHall. This problem has happened on COOP 18 - COOP 19 and GUNGAME servers. did not crashed on Realism server.
So to avoid you, time consumming, fixing this, maybe is best delete this campaign from all servers or maybe the best option isdelete it only on COOP 18 - COOP 19 and GUNGAME.
Maybe can be replaced for another campaign on COOP 18 - COOP 19 and GUNGAME
see ya
