So my server is set up to continue generating a nomal world. I haven't generated any new chunks since 1.13, and now any NEW chunks are generating as a superflat world... I can't find anything about this so I must be the only one having this issue?
Seen in the photo it just randomly decided it wants to generate superflat
I will note that the machine the server is running on crashed once. Only once, prior to the world generation issue.
