/locate and eye of ender find strongholds in invalid places

This issue blocks MC-110531.

Apparently affects /locate as well (at least in a void superflat world)

not fixed in 18w15a

Still in the 18w15a.
Eye of ender can still use in End and Nether.
Mod please reopened.

Still and issue in 18w16 A, only now I can't seem to find strongholds anywhere. and /Locate fails to work as well.

I don't believe this bug to be deterministic. Both me and someone else on what is probably a duplicate ticket looked for strongholds at the exact same coordinates, as reported by the /locate command: 8 ~ 8. Ender eyes also pointed to that place. However, after reloading the world, I got correct coordinates and was able to locate an actual stronghold.

Bogdan, are you talking about mine? I didn't know this article existed untill it was listed under "is duplicated by" even though I searched for this issue.

Anyway, the stronghold doesn't seem to generate when the chunks are loaded in survival. But it does generate when you load the chunks in spectater or creative. Here is the seed my single player survival world used: 2614790235376886615

I can't confirm generating when in spectator or creative mode, like previous commenter said.

I tried using the locate command, teleported to the location, set gamemode to spectator (tried creative aswell), stopped the server, deleted the file containing the chunk in world/region folder to force the chunk to regenerate, started the server and logged in again. The chunk regenerated but there was still no stronghold generated. I deleted the right file. Structures I set up there for testing successful deletion got deleted as well.

1.13-pre2

Seed: -9193889702175967349

Location generated by locate command: -1832, ~ , 1176

can reproduce in 1.13-pre5

can reproduce in 1.13-pre6

Can reproduce in MC 1.13-pre6 too.

@unknown @unknown If you have a reproductible case, can you send me the seed, the spawn location and what /locate returns ?

@unknown I checked with your seed and coordinates. It actually does generate a Stronghold room, but is missing part of the stronghold itself. Can you confirm that ?

Working now. I created a new world to reproduce it but... seems to work correctly.

Seed: 7686493379246203685

I checked again in a newly generated singleplayer world in 1.13-pre6 and can confirm there is a Stronghold room but most parts of the stronghold are missing.

This does not appear to be fixed. My report for Pre 7 has been marked a duplicate of this report. https://bugs.mojang.com/browse/MC-133276 

Please send the seed/coordinate combo, otherwise we won't be able to reproduce for pre7.

@HexxiumGamingYT, your report hasn't been marked as a duplicate yet. Someone just commented that your report was a duplicate.

This ticket only covers finding strongholds in worlds that should not have strongholds. This ticket is not associated with your issue.
