Craft on surfaces disappearing and/or sinking into terrain at random

My first mission in KSP2 was a mun landing with Bill in it. The landing was a success, but an unrelated mission-ending bug forced him to be stranded there.

So, I decided to go rescue Bill with Tim C, but an unrelated mission-ending bug forced the mission to also strand itself near Bill's ship as well.

At some point during the approach, though, Bill and his ship sunk into the terrain while I was landing Tim C, and he ended up 2 or 3km below the surface by the time I noticed. Tim C would've landed about 200 meters away from Bill's ship otherwise. Either I didn't attempt to switch to Bill, or I was unable to (I don't remember which), because I didn't focus on Bill's craft. Similarly, a spent stage from Bill's craft that landed near Bill is also missing.

My next mission was a Minmus rover with Valentina, which successfully landed, but due to another unrelated mission-ending bug, the rover was unusable on the surface. After kicking it around in the low Minmus gravity with Val on EVA, the rover blipped out of existence on contact with the ground. I don't think I tried to search for it in the tracking station. An interesting effect with this specific bug though, was that the distance indicator stayed fixed on screenspace at 17m, instead of moving around the screen when you move around the camera or Val as expected. Val's still on the surface in EVA, but the rover is gone.

This type of bug is probably the biggest deal, because although the other mission ending bugs were mission ending, those were at least fun to try and work around, whereas this kind of bug presumably just deletes your chances of survival. Otherwise, in my opinion, the game's bugs have been fine (charming and enjoyable, even).

I had the same problem with a lander that didn't have enough fuel to return to orbit.  I sent a rescue mission just to find the first lander had sunk into the surface.

Well, colonies are coming someday, and the scientists always told us that colonies on other worlds would have to be underground to shield from radiation...
