weird water canyon/cave spawning

I personally believe that this works as intended.

i don t think so there are more reports of this

... what's the bug?

Edit: To clarify, these are aquifiers and are supposed to intersect all kinds of caves. Personally I don't think this configuration doesn't look weird at all, I can see why it seems somewhat messy to you but in my eyes this isn't a bug.

Also for the future, please remember to include seed + coordinates when reporting world generation related bugs. Thank you!
