Parachutes don't disappear

[SamuelV]

I've had two parachute landings so far and in both cases the parachutes wouldn't disappear after the landing (see attachment).
The only way for me to get rid of them is to save and reload the game.

Please fix. Thank you.

If you have a savegame where this can be repeated that'd be great! Altho the screenshot gives a few clues so maybe we can work out what happened.
