World Generation on 21w06a

The world generation is a little weird on the new snapshot (noticed it only on the surface, the caves seem fine). Obviously I know it's absolutely normal, but I also know snapshots are released so they know the problems and I thought I'd share.
I have encountered around six blocks tall dirt pillars and some things that look like chunk errors (the one attatched).
The one I attatched has the seed on it also, that seed was kinda messed up.
