[Bug] Lag caused by specific Seamoth.

I was wondering if anyone else has encountered this bug. Better yet, if anyone knows how to fix it.

I experience lag caused by a specific Seamoth. This Seamoth - let's call it Uno - is the one I've been using since I got Subnautica in January. For 40+ hours of gameplay, Uno hasn't given me any issues.

Recently, however, riding around in Uno would cause lag. The game was still playable, but it was of course annoying. Docking Uno inside of my Cyclops would cause even more severe lag. With Uno docked, walking inside of the Cyclops would be unplayably laggy, and driving it would also be bad.

When Uno was not parked inside of the Cyclops, the Cyclops was fine.

I built another Seamoth, and that one works fine. I can ride around in it, I can dock it inside of my Cyclops, and the game runs normally. I removed all the upgrades and stored items from Uno and put it into my new Seamoth, which is now configured the same way.

Does anyone know what causes a specific Seamoth to make the game laggy? Or does anyone have a solution that doesn't involve building a new Seamoth each time it causes lag?
