[BUG]Hole in Emerald

Was playing arena on map Emerald and found this hole near the rocks around the left side of the Blood Eagle Base. Not sure if mentioned before.

the rock might just turn white :x

Does it look like that when you're right beside it?

Yeah it does its not the rock up close, its the terrain.

Known issue, thanks.
