This is a very well known bug from private servers, at least for me. Whilst flying on a flight free zone, press space (glide hotkey), cross the barrier to a no flight zone, then press space again. You get licked in midair:
there is still this issue and sometimes can let you glitch into the ground. maybe you can force the wings to close automatically if this situation is happening. it happens everytime i glide from a fly zone into a non fly zone and press the space buttom while gliding
