Hello again :D I found some bugs for you to squash.
Truck groups don't get carried over when blueprinting a truck that's been assigned to one. Bit of a hassle when pasting dozens of trucks and having to manually assign each one as "Cargo Trucks" or "Fluid Trucks".
A visual bug, when a truck is fulfilling a wait condition (say, 10 seconds elapsed), there's a portion of the progress bar that has vertical lines on it that doesn't fill with the same orange color as the rest.
Another visual bug, I noticed when the truck turns that the headlights sometimes detach from the vehicle!
Hello again, and thanks for the reports! I'm on all three: truck groups will carry over in blueprints, I'll fix the wait condition progress bar, and the headlights coming off the truck on turns.
