I got 3 mail vans stuck up in front of a bus stop.
I think it was caused by having 2 road vehicle depots in the same town, the buses switched destination between the next stop and the depot continuously. I got a lock-up of 5 vans untangled last time, but unfortunately I just cant get the mess sorted out this time, the vehicles just wont move

since the stop is in the middle of the town, I could build a heliport to get the mail out, but helis wont carry mail
Id be glad if someone could manage to un-tangle the 3 vehicles, I already removed the secondary depot from the town and deleted a few vehicles.
the vehicles affected are the only 3 mail vans I got right now, the lock up should be on the screen when you load the savegame, just turn on invisible buildings
thx to anyone who can help me
