If it helps, it appears that the hangars stay present, but we cannot demolish them either. Just say "you cannot demolish this building" when you try to right click.
In addition, the hangar capacity shows 2/0 or 2/1 if I build a new hangar. This corresponds to the amount of planes I already had at my satellite base prior to the patch going on, and not in regards to the actual number of hangars I have.
Not sure if a savefile would help to look at and see why the code things the hangars are "untouchable" or just don't plain exist? This also seems to be tied to the satellite bases, as my main one still shows 4/4 for the planes to hangar ratio.
