Fuel Station II Idle Issue

Issue description

I have a Fuel Station II with multiple assigned trucks. After working for a bit, at some point all trucks will remain idle at the Fuel Station II they are assigned to, even if vehicles on the map are out of fuel (tree harvesters, excavators, etc).

The strange part: manually moving the truck to a location a few pixels over somehow "jump starts" them into remembering to do their job. Each one that gets manually moved then goes off to do refueling tasks and works as intended for an unknown amount of time. They eventually end up idle again, though.

Reproduction steps

1. Load attached save.
2. Find Fuel Station II, notice all assigned trucks are idle in the near vicinity.
3. Go to Alerts, notice Tree Planter, Excavator, and Small Excavator are all out of fuel.
4. Go to Fuel Station II, select an assigned truck, and manually drive it anywhere (one pixel over, doesn't matter the distance, just as long as it moves).
5. The assigned, and now manually moved, fuel truck suddenly remembers it is supposed to refuel vehicles, and departs to do exactly that!
6. Wait an undetermined amount of time. The assigned fuel trucks will all eventually "idle out" again, refusing to refuel until manually moved again, and which point they work (for a while).

The only problem is with the combination of a fuel station II and a pickup. If you assign a truck, it works.

This is because pipes obstruct the fuel station, and the trucks are desperately trying to park in front of it which prevents them from ever getting a refuelling job. Removing those pipes, fixes it.
