/locate ruined portals isn't always right

I have experienced this phenomenon also. I suspect that the problem behavior is caused by the user searching for the portal in the Overworld but the /locate command is giving Nether coordinates. I suspect this becomes a problem in this release because Ruined_Portals can generate in either the Overworld or the Nether and the /locate command offers no parameter for specifying the present dimension or a different one. I will investigate further and offer an additional comment once this is confirmed.  Investigation continues below.

I used a portal to go to the Nether and /tp to the coordinates given and there was no portal, ruined or otherwise, at those coordinates at any altitude. I returned to the Overworld and tried the original search, but inverting the sign on each of the coordinates, and teleporting and searching at all altitudes for the new coordinates. No Ruined Portal was found.

The original /locate Ruined_Portal command was issued from coordinates 146. 86. /-383. The returned coordinates were "/---576. /~. /-1104 1019 blocks away." I can attach or make game world files available if requested.

Note: The game world was originally generated by a 1.14 pre-release shapshot and contained previously loaded and modified chunks before being updated to snapshot 20w16a.

@unknown please use the project linked below, as you are playing a different version of Minecraft

Minecraft: Java Edition

@Celesian Thanks. Embarrassing. Will do. I found the MC Java edition issue: MC-179029. You or someone may want to link these issues as possibly related.

Could someone affected please provide a seed used and the location you ran the command? (Not the location the command gave you, where you ran it, so someone else can reproduce).

Edit: It would also help to know if your world was created prior to the BETA's and updated or if it was a brand new world created in the BETA.

@IonicEcko, 1273368191 is the seed I use, and if you write /locate ruinedportal, you get 696, ?, 24 or something. This turns to be underwater, and if you look all the way to bedrock, you still can't see the portal. I tried digging a bit in all directions, but still can't find it. Hope this gets resolved soon

According to https://www.minecraft.net/en-us/article/minecraft-snapshot-20w16a, they sometimes spawn underground or in oceans.
