Started expedition which is now stuck with helicopter on pad @0% for over 15 minutes, all the assigned staff are not visible and when you click on them in the staff pahe it says they're awaiting expedition.

I've tried reloading, shutting the game down and restarting but nothing works its resulted in a pad being completely unusable and 3 staff members being gone too, I also cannot complete the expedition which is an obstacle and needed to further progress
