Boat carousel no longer works

Using the nautopilot you can make boats form a carousel of sorts. I have one in my world. It no longer works upon disconnecting. I come back and it is broken, at first I thought it might have been a random error, but after I rebuilt it and disconnected it was once again broken with some of the boats totally destroyed.

i know this is a really specific issue that probably nobody is dealing with but this is really special to me. My world generated with a large lake in the middle and the boats spun around in the middle that helped me travel around and now it doesn’t work.

The image below is of my boats all stopped. I put moonlenses on the boats so when you open the map you can see it spinning in real time.
