Ocean Monument spawning in River biome

Thank you for your report!
However, this issue is Invalid.

Your game, launcher or server is modified.
If you can reproduce the issue in a vanilla environment, please recreate the issue.

• Any non-standard client/server/launcher build needs to be taken up with the appropriate team, not Mojang.

• Any plugin issues need to be addressed to the creator of the plugin or resource pack.

• If you have problems on large servers, such as The Hive and Hypixel, please contact them first as they run modified server software.

Im a bit confused, i was running the vanilla game? I will delete the chunks with MCA Selector tomorrow and try again.

John Sullivan can I get the world seed?

Sorry its midnight here in the UK, i will post tomorrow morning

My apologies, you can cancel this one. I'm not sure what happened, it may have been from an earlier snapshot, I recreated the chunks and now it is fine.
