Pillar of floating Grass

Hey everyone,

This one has me stumped. In 4 spots on my map, there are pillars of floating patches of grass going straight up. I’ve deleted all the Foliage grass and made sure the Z axis on the original mat is 0. Anyone have any idea how to fix this. At first i thought it was because I altered the terrain with grass on it and it glitched out. But I have flattened my entire map and it is still doing this. Can’t click it with the selection tool in the Foliage tab either. Any help would be fantastic!


Also, not sure if this is the right section for this post, only logical one I could find in the forum.
