Hi there, I may have not explained it properly. To explain it again, when I was playing on a world I found that the bottom of the world (where the bedrock stopped generating) was Y=-2, or two blocks below 0. Not only that, you can place blocks below level 0 to -2, which tells me that for some reason the world limit on the Y axis going downwards is two blocks lower than they are supposed to be. I tested this in the Nether and End and the problem also exists there. To reproduce the issue, here is what to do:

1. Open up a Minecraft world on 1.16.100 and go down to Y=-2 (X/Z doesn't matter) in Nether, Overworld or End.

2. You should see that the bedrock layer is just above you, and if you go to Y=0, you can see that there is a bedrock layer beneath.

3. Try to place blocks beneath Y=0. This better works in the End. You should not be able to place the blocks underneath that level, but you can and it works with every block.

I hope my explanation was useful. If you need a cleaner explanation, I can give you a clip of me doing that.

Thanks

Mr Kirby

I was unable to reproduce this on iOS in the overworld in the 1.16.201 Hotfix. Was the world you did this in made from a specific template?

Thank you. But sadly, the computer my world is on is currently in a state where nobody can use it that well (it freezes all the time, takes half an hour to even do anything, and it has a horrible CPU). Minecraft probably can't run on there any more so unless you know a way to transport worlds over to other computers, I can't access the world anymore so sadly this issue will have to wait until someone else reports the problem or it is looked into. I appreciate the help, but I'm afraid my worlds are on a slow, unusable laptop so I don't have control over this anymore.

Thank you for your report!
