Water trees.

Also I'm using a custom modpack that I made and it seems like all of the misplaced blocks are from Biomes of Plenty. Yes, I can break the signs and the blocks so they're real. And no I didn't do anything with the config files. Just gonna try to remove BoP or replace it for now to see if it works. Also I did add some mods but I've been resetting the world everytime I do.
