Weird world generation

[AaroSA]

I recently started hardmode in one of my worlds and went to smash some demon altars. Saw something that was somewhat silly, so I deciced to share it with you

Yes, that's the Hallow spawning on a natural Crimson.
Has something like this happened to you anytime?

Literally every single world of mine ends up that way. Nothing special.

Its happened to me a few times, I always find it entertaining when a corruption/crimson biome is turned into a hallow biome.

The world im currently playing the ocean on the right side is like 20 blocks higher then anything around it.

Actually this happens to me quite alot. A weird world generation that happened to me was in 1.1. I created a new world and the spawn was in the middle of the jungle.
