Freighter/Corvette Walls Bug?

Can't find it on a search so apologies if I missed it, in advance.

Since the Cosmos update (I believe), when I warp/portal to/summon my corvette or freighter, it has a good chance to be bugged--the Corvette will un-snap its hab/cockpit etc, so that there's walls blocking movement through the corvette, and the Freighter will do much the same, re-erecting walls between all modules. There's no way to really fix this (since I'm then stuck ex. in space with a broken ship, unable to get into the pilot's seat, or stuck in my portal room for example on the freighter), except by reloading an older restore point.

It's happened five or six times now and it's starting to worry me, because if I end up not realizing one is broken, it might completely brick my freighter or corvette and necessitate another Freighter base reset or a complete corvette rebuild (it's too decorated to allow me to simply re-snap the modules in a station).

Is anyone else having this issue? Is there a way to avoid it, a known cause? Or is my save file acting up? Thanks!
