When time permits, maybe in a few weeks, I hope to be able to trace through one submarine, the turms available for it, and the equipment that attaches to both, for date conformity. If I get one sub down, and then try to build a script to check the others, it might speed things up a pinch... maybe... There are quite a few variables to this equation...
Another aspect of the "upgrade" process involves the fact that the player might have a new radar or radar detector device that might not be available in the new boat, or maybe it is a "bonus" item that they paid renown for. Most items like that will not transfer to the new boat or turm. That is not a "bug". The boat not moving most likely would be considered one...
If when you encounter anything, be sure and let Fifi know the boat you're in, the location of your home port, the date, and the boat's configuration, as far as you can remember. The more info, the better. If you can get screen shots of issues, or even a video, all the better. Thanks
