This problem exists in 1.18 Pre 7. In one area the terrain generates floor to sealing even taking out part of the floor. Also added pics of a bunch of areas I found. Seed is 4132146605620838058 on pre release 7
Also terrain is generating on the lower roof on the outside.
this issue first came to my attention personally in June of 2020, the original post was in August 2019, and now it's March 2021, almost a year and a half. Can we please get some sort of update on the status of this issue? I and many other Minecraft players are paying for realms and as such I believe we are entitled to know whether or not this issue is even being looked at. If this issue is being ignored and pushed under the carpet as it were, I am inclined to cancel my realms sub. I understand that realms is probably not the highest money maker in the Mojang arsenal, but I feel like it's bad business to ignore the issues your paying customers are having. I apologize if this comes off as slightly confrontational, but I have put up with this issue for almost a year and multiple updates/patches have been released in that time and I feel like this is being ignored. If we can get some evidence that it's at least being looked into that would be great.
I am on 1.15.2
I have been trying to upload a world to my realm for almost 3 days now. on my bigger world it gets to 10.9% them give the "upload failed (-1)" error. I have tried with a brand new world and it gets to 100% but still fails with the error "upload failed! (500)" I have uploaded a screenshot of both. The big world has datapacks, although I tried taking a copy of it and removing the datapacks completely and then uploading with the same result. The world that gets to 100% has no datapacks and is very small. I will keep trying, but hopefully the Mojang team can figure out whats up. Best of luck!
Edit: I just tried resetting the world with a new world, not even uploading one and it comes up with "null - 0" I don't know whats going on.... I can switch between the worlds that are already created on realm (I have all 3 slots created) and I can do the world templates, but can't create a new world or upload one from single player.
I tried to find others before posting, but I can't navigate the bug tracker very well lol. I went and added all my screenshots to the linked bug tracker. Thanks 🙂
