In Bungle wasteland I have two helipads. Both of them are stuck on leaving to the expedition. They are waiting on staff. I have quit the game and restarted but nothing changed. I can't delete the helipads. 
One is stuck going to Laser Labs, and one is stuck going to modification lab. 
First the laser labs was stuck, but I still could use the other helipad a coupe of times, now the other is stuck and is in waiting mode. But the staff aren't goining to the helipads. When I look in the staff list the status is: Leaving: Expedition. But they don't. Some of them are in the helicopter and some are just standing still in a room or wandering around. I also can't pick them up or assign othe staff to the expedition.
