I got a ship unit "stuck" and not moving in Showcase: Ford Class scenario. Ordering new speeds or course doesn't help, the ship is reporting speed 0. This is not a completely new issue, I experienced problems with movement of naval units in the past in various scenarios, but this time I've a save, and it affects one of the key units for this scenario so I may need to start over if there is no workaround

The unit in question is T-EPF 12 USNS Newport (screenshot). See the attached save file.
Is there any workaround to unblock it?
