I really don't think they look that good either, and makes the terrain look very jarring. I guess I'm also weirded out by the lack of smooth transitions between land and oceans due to the world generation changes.
I'm surprised this hasn't been fixed yet. I'm somewhat hoping it will be.
The credits is something that likely won’t be changed, but from what I’ve seen, the credits could be made to be a little tidier, such as listing people’s names under specific categories and such.
I might close this because so far from what I've seen in 21w42a, the terrain oddities seem to not apply all that much anymore, but I will keep looking in case anything looks particularly unusual.
