Service vehicle gridlock: All-way stop


2 simultaneous left-turning (or u-turn) vehicles at a ±shaped intersection will cause a gridlock.


Do you have any screenshots of issue?

Both catering trucks trying to turn left. Both attempt to occupy the first ‘spot’ in the turn, and then they’re stuck until the “un-stuck” algorithm kicks in, which by that point you have gridlock if you have any + intersections in your airport.

Yep that happens all the time for me too once traffic gets a bit heavier. But impossible to report because it’s gone after a reload (I had reported it in the past though).
Temporary you can help yourself with the F10 menu and “Unblock all road nodes” but of course you have to do it every time this happens.
