i think you get this when some changes are done on actor.static on a map, and you load a mission using an object deleted from this map with an actor.static modification...

if you are using a new version of a old map where you have missions, put out the actor static file to male il2 use the stock one.

or the mission must be redo including changes of the new map.

if i don't mistake :-?
