So i teleported on a large/very large arctic planet, and the world generation was really broken.
The backround was glitched on many places, and the "surface" was in the middle of the planet.
Everything else seems to be somewhat ok...

The "surface" had right backround and everything, but not far above it begun the "underground" section. Above it was lots and lots of ice and slush, breaking the backround blocks there made water spawn. After that was "real" arctic ocean was above it, and really deep. (not sure if there was islands spawning, i did not check) Also it had this broken, 1 colored backround.

I teleported back to the "surface" to see what was below it. There was this small layer of "underground" and soon below it was a large layer of the planet core zone. Nothing else really.

Yea.
Tell me if anyone else is experiencing this
