I completed my repair base level 3 upgrade, still getting the message that I need to upgrade to repair my plane. Opened & closed the game, still getting the message. This is the first bug that is REALLY impacting my game.
I went ahead & dropped it and bought another one. But I can't afford to do that any more. I'm sure the devs are reading these posts and it will be fixed in one of the future updates.Happen to me too. My level 2 repair base cannot repair Owl.
