Any problem that @KorgFoehammer doesn’t experience and other players do is caused by stuff those players installed on their computers. Only problems experienced by @KorgFoehammer are real, and those are caused by devs listening to other people instead of him.
My personal experience is that I still fall through ceiling tiles but not foundations. Though these days I don’t log out on raised foundations. Only ones that are close to ground level.
Edit: To be clear that happens only when logging in. I haven’t fell through a base while actually playing in some time. Though I haven’t been playing that much either.
This is what I’m referring to. If you’re being popped back into the location you’re suppose to be after loading in, particularly when built over water, this is pretty normal.
That being said, my clanmate has now died twice on server resets in the past week or so.
Lately when I fall through the ceiling upon logging in it’s permanent. If it’s into an enclosed place, such as under the base due to having ceiling tiles as the bottom floor, I have to break a building piece or pull the bracelet to get out.
Used to be amusing to log in on a lower floor than I camped out on, wait til everything loaded then hit jump. Was like literally jumping straight up through the ceiling as it warped me back to where I was supposed to be. Now that doesn’t happen. I stay on the level I logged in on.
I have to wonder if this may be what’s killing some people. Perhaps some fall through the map itself and the anti undermesh code zaps them.
Possibly. However, my clanmate died once while logged out on near solid ground… so not sure about that. The first time she died was in an area built over water. That could be explained as potentially drowning, but not the second death.
On siptah, I log out in my ship build, but I don’t drown. I swim up and snap back into the ship.
Exactly, it cannot be drowning. Even in dregs when the water rises, if you won’t move, you ain’t going to drown. The water works funny.
But log in dead is a really rare bug that happens individually.
Unfortunately, your dear Marylambs is experiencing a unique bug that you ain’t going to experience in these servers you are regular. I don’t know if Zendesk can do something about it.
I remember @Lordgangsta29 years ago on an American server had this problem. Me and @Bandit_Leader never experienced it. I had some logs in with low hp, like i was getting falling dmg, but never death. It was on 2020 if i remember correctly and i started sleeping completely naked, all the inventory empty and on a rug, not on beds. Funny thing back then that i bought the Derketo dlc for the bed and i couldn’t use it (what a myth today that dlcs were coming flawless… same ■■■■ different day 
).
Pass my greetings and condolences for the issue, i really hope it’s not persistence, because it’s a freaking annoying bug.
