Hole in terrain Dry Fang Canyon

Playing on a community server and ended up finding a hole in the terrain in Dry Fang Canyon. In can get into the hole 100% of the time, as long as you are small enough and can reach it.

The hole gives access to out of bounds areas of the map and the void. Going into the void area teleports you to the surface or into more hollow, out of bounds areas in the terrain.

You are definitely not supposed to be able to gain access to the out of bounds areas of the map. If the hole didn't exist, that part of the wall would just be the same as any other.
