I’ve purchased many more slots than I have aircraft in each category but still can’t make any of my aircraft depart. No available destinations. The destinations slots show that an aircraft that is now waiting to depart is “At Airport”. Multiply that by 30 small and 20 medium.
The only way out of gridlock I’ve found is to kill and relaunch. That suggests to me that this is a bug. Anyone found a way to make slots reusable without restarting?
