Hi, I'm having an issue where flowering pots are spawning randomly and excessively in different parts of the world and it's crashing the server. How can I fix this?

I have no way to reproduce this, so I'm going to share it around to see if anyone who's had a similar issue can reproduce.

You can attempt to bandaid fix this by backing up your server and then disabling colored flower pots.

Which Forge Version are you using?

1.12.2 - 14.23.5.2772

I'm going to attempt bandaid fixing the server and hopefully it helps. Thank you for working with me on this.

Do they appear in newly generated chunks only, or anywhere including existing chunks?

That looks like the old ID-mismatch problems, but I thought the new system had squelched those.

the new systems doesn't fix that issue. They did fix one of the rootcause of world IDs corruption earlier this year, but without more logs and answers from @ladyGique we won't know for sure...

This is definitely an id mismatch. We can't help those.
