Guardians but also witches aren't spawning in pre-1.18 generated monuments/swamp huts i.e. farms. It is simple to recreate: open up pre-1.18 world with already generated monuments/swamp huts in the new snapshot.
This issue comes to light now this bug was fixed, so i'm not sure if this specific issue came with the first or latest 1.18 snapshot: https://bugs.mojang.com/browse/MC-237986

Can confirm, same issue happening to me.
This is a witch hut: 1.17 world, chunk generated in 1.17.1, upgraded world from 1.17.1 => 21w44a directly.
Just when I finally thought I could directly compare the rates pre+post 1.18. I have a feeling 1.18 is going to be much lower from what i've heard.
Side note... there is still no bedrock, at least not on chunks generated in 1.17.1.... going to find that bug which i'm sure is open, too..

Also applies to Pillagers as per MC-240716
@unknown You are the reporter, so you don't need to comment the affected versions, you can add them directly.
Same thing for Pillager Outpost -> not spawning pillagers
Guardian farm -> no longer sees location as "monument"
Using old map (1.14) in 1.18 pre-1
I am still experiencing this bug in a world that was upgraded from 1.17 to 1.18 pre 1 and then to 1.18 pre 2.
@ Gabriel Pascal Johnson, does the bug exist if you upgrade from 1.17 or 21w44a directly to 1.18pre2 ?
