If you have a backup that was created before this update and hasn't been opened during this update, then simply do not open the backup until the bug is fixed. Changes and bugs only affect worlds that have been opened while the they are still in effect. Once the bug is removed, it will be safe to open it without the bug occurring.
The game says that I am at like y=110 even though I am right above the sea (which, under normal circumstances, is at y=64), just to confirm your suspicion, Gruntastic. Also, I get the feeling that this bug and another one where new worlds cannot load chunks below y=0 are related to each other.
The same thing happened to me. on Android. All my items are gone, my wolves and horses died, with messages popping up saying that they suffocated in a wall. My villagers are gone, probably met the same fate as my wolves and horses. The game somehow reverted back to the old y-level system, where the game considers y=0 to be the bottom of the world rather than y=-64. My base is just above sea level (y=64), but the game says that I'm at around y=110. The clouds fly right through my base, even. Also, I am going to ask you to please be respectful about this. This is a beta after all and we are beta testers. We are to expect that with each new update there is a chance that something may go very wrong (and usually something ALWAYS goes wrong). If you are not about dealing with these sorts of things, then maybe the beta program isn't for you. Also, and I just realized this myself, if you do not want to leave, then I would suggest copying your worlds before updating the game. That way you can test to see what's happening while having a backup in case anything goes wrong.
This happened to me too. Though, most notably, you only teleport if you are underground when exiting the game. If you are above the surface, you do not teleport at all.
