with the new world gen there are always bugs... using version 18w07c play this seed -2301372194407171657 not sure if it works on any other versions
That's definitely very broken. What do you mean by new world generation though? Just because of the new things?
What's broken about it? Got any screenshots?
It's looking perfectly normal to me so far, except for the seaweed and fish which are new to me and I found 2 birch trees growing diagonally adjacent to each other which I've never seen (or at least noticed) before. (And I did test it in 18w7c.)
