I'm having a problem with in FS2 with custom missions I make (I'm have the latest patch of TBP).After several minutes of playing all the ships will suddenly become immune to weapon attacks of all types,everything shot that at them goes right through the ship without having any effect.The ships still take damage from collisions,only weapons fire has no effect on them.
I've had this problem before,always on missions I've made with a mod.It occurs more in missions with larger numbers of ships and at times has made "ghost ships" to appear (i.e. exact model duplicates of ships in the mission which are not targetable,and everything flies through them.)
I've done several searches already to see if anyone else has had this problem but found nothing rellated.Any ideas on what's causing this?
