I posted previously about the trailer not showing the fill progress. After I empty and start filling again, it shows progress. If I save with partially filled trailer and save then exit. When I load that save, the filling progress does not register until I empty and start filling again. So, it appears this bug is related to a partially filled trailer does not show fill progress on load, but will show progress once empties.
