Current issues: 1. When two trucks collide while pathfinding and become entangled, there is a small chance that they will remain stuck, unable to break free from each other. 2. When a station is assigned to an idle truck that has no active transport task, the truck will pointlessly move in and out of the station repeatedly, rather than simply remaining at the station to await a new assignment.

Thanks for the report! Both are fixed in 1.1.3:

1. When two trucks block each other, one of them now always gives way: it backs off and waits for the other one to pass, so they can't stay stuck.
2. A truck whose next stop is the one it's already at now just stays there and waits, like a train with a single station, instead of driving out and back in.
