Since I opened my save game yesterday, my passengers just stopped boarding - I hadn’t made any changes to the airport, but the flight status just gets stuck at ‘Go to Gate’. All other turnaround services complete as normal.
Passengers check-in, make in through security into he secure zone, and then just sit by the gate and don’t board. I reverted to closing all stands and opening just one to test pathfinding etc. and no problems there.
At the time I posted this I had one stand open and seven cabin cleaning trucks - none of them were assigned a job! I’m having a similar issue with baggage loading now…I’ve posted another thread about that to keep things clean.
