My Airline (3799) seems to have a DC-3 that will not get reductions in how many hours it flies. It seems to be stuck at 20 hours, I know this because I added a route to Prague, it was at 20, I added a 3x to Slovakia, still at 20. I guess some airlines have a bug in which their planes have the hours (frozen), and they're expoiting it. I should not fit any more flights, I won't be able to afford it anyways.
I am also wondering. If the hours do get fixed. Will those who exploited the bug have the routes shut down? Or will they still have them open. Might create a tad of an unfair advantage if it dosn't happen.
