The lag when trying to generate a buried treasure map also caused a map to be deleted in one of my worlds...
This should not be "Works as intended," because the ancient city isn't generating correctly. The /place command should place structures as if they were to have generated naturally. And this isn't something that wouldn't be to hard to change, either, considering how structures such as mineshafts, end cities, and nether fortresses overwrite blocks. I don't get why ancient cities don't overwrite blocks. Ocean Monuments won't even generate unless you are in an ocean biome, so why can't ancient cities generate how they should generate!?

This is not a duplicate
this has to do with an ingame setting, and has nothing to do with the launcher
plus, the issue that you marked this as a duplicate of doesn’t even mention anything about the issue I found
Must have been sheer unluck if I couldn't find any when you could
Happening in 1.17.1
This bug has appeared on Java as well
Can confirm 1.17.1
I could not find that when I was searching so I assumed that no one posted on the issue

No this is not a duplicate
Mark as resolved: Did not realize it was already fixed
I think it has to do with storage space on the hard drive
I was having this problem until I removed some of my files, thus freeing up some space on the hard drive. Haven’t seen this problem since. (I was also using the old launcher)
