Happened today on my 2 player Bedrock realm I'm version 1.19 main release. It all entities, including the ones in my mob spawners. I actually made a backup specially for this release to test.
You login it works just fine and all are present. Once all users log out they get Thanos snapped.
This issue ended with the hotfix and re-emerged after full release.
These issues are similar but unrelated. The resolution steps suggested also do not work. This is biome dependant as well, meaning when I leave the Ancient City it works just fine.
Issue is still active. Mineshaft spawned above and the mobs are spawning on blocks below the Mineshaft as well.
Hi - The main issue doesn't link to MCPE-98789, The chief complaint in there was "void" and these are all Overworld issues. The overworld is unaffected in this - it only affected the nether and filled it with Netherack - not VOID. Furthermore, this issue still persists. Please take a look into this - the issues are most DEFINITELY unrelated to overworld generation, but nether generation.
I can reproduce this by throwing an Ender Pearl to the middle right of a nether portal frame properly while in the nether. Inversely, Throughing pearls in this way at an overworld portal divides your coords by 8 teleports you there in the overworld. Video to come.
