Truck delivery problems with experimental

I'm trying to make an excavator, but my trucks won't deliver vehicle parts II to Vehicle depot II. This has worked like a charm before. I've checked everything I think: All buildings have power, storage has truck export set to ON and is full, vehicle depot has truck import set to ON and an active production order, all building have workers, there are several trucks idle with the "no job" status, the pathing works. I tried destrouying and rebuilding the Vehicle depot II, that worked, all vehicle parts II were delivered for the building construcion, but not for the vehicle construction. Is this a bug? I just started using the experimental version.

Nevermind, got confused by both vehicle and construction parts being yellow. I'll go to bed now.
