However, the stuck vehicles wreak havoc through my airport, because they are still allocated new tasks and the planes that wait for them are subsequently stuck at the gates.
It seems I can’t remove the stuck vehicles through the F10 menu, and also saving and loading doesn’t help. Is there any other way to remove them? I have also tried to remove them through the vehicle list, and they are no longer on the vehicle list, but they are still sitting on the tarmac. Are vehicles no longer assigned new tasks once they are off the vehicle list? How many stuck vehicles make my savegame bugreport-worthy?
Mixed results: One of the four trucks seen stuck in the picture has disappeared through selling + save + load, two have disappeared during the next 24 hours (timeout?), and one is still there after at least two ingame days.
Then I would F10 “reset road nodes”. Press it 10 times if need be and maybe combine the 10 pushes with a save/load in between, after, etc… most stuck vehicles will get loose after a combination of both.
