This does not happen immediately when loading a mission, but when exiting a mission, when you return to the map.
The disappearance of objects occurs in an area always in the form of a rectangle, but sometimes the user may find a completely white (empty) 2D map!
At the same time, if you bring the camera as close as possible to the problematic area, then the objects appear again, but this will only fill a small area, there is no way to fill the whole map at once if you lost a large area.
