3 years ago @rawora-rg I've reported the issue to Paper with Steps to Reproduce, so we can hold off working on this for now:
https://github.com/PaperMC/Paper/issues/5773
I'm adding a "Blocked" label to this ticket pending the response from the Paper team.
Short overview of the issue
For still unknown reasons, players are able to cause Bedrock to be removed by spawning Nether Portals near 0,0 in the Nether. This may be related to our slightly glitched map and/or 0 seed.
I've asked around and no other servers are experiencing the issue, and it seems to be limited to the spawn area, as I've not been able to get it to happen outside of spawn yet, but it's possible it's happening elsewhere as well.
Nether Portal spawning should be deterministic and should not happen below y4, due to how MC's Portal Spawning mechanics work, so it's very strange that this is happening.
Proposed Solution
We should either block Nether Portal spawning if it's spawning at a certain y level, or potentially replace Bedrock that is removed by the Obsidian frame of the portal (not as good of a solution).
Is this issue new / recently noticed, or something that's been happening for a while?
This has been happening for a few months, but has become worse in recent history as more people have been made aware of the issue. I'm sure opening this bug report will not help, lol.
