Graphics Glitch in Tanaan - possibilities yet to be explored

[Obsolus]

Requirements: Mechashredder 5000. Not sure if Aviana's Feather works or not.

1. Go to Zorommarsh in Tanaan - head to the west side and enter the Cave of Betrayal
2. Enter the middle of the cave, where the captain's treasure chest can be found. The one that spawns Glub'Glok.
3. Look UP - There is a large hole in the roof with light beaming through it. You can see a tree growing on the surface above the cave.
4. This hole does not actually exist and neither does the surface above it. Hope into your Mechashredder 5000 and fly straight up into the hole.
5. You will immediately be disconnected. With a bit of luck, after logging back in, you will be stood in the textures between the cave and Tanaan's surface.

Due to the cooldown on the Mechashredder, I have yet to explore this glitch properly - maybe you guys can help. I'm going to be testing out goblin hand gliders with this to see where I can get.

I believe the reason for this happening is because of an early rendition of Tanaan's map that originally had the hole that connected Tanaan's surface and the cave and has since been re-textured/re-landscaped over the top and the designers have forgotten about the hole in the cave. Alternatively, the interior of the cave has been copy/pasted from somewhere else in the game (as they do quite often). I believe the latter to be most likely due to the fact that the tree you can see outside of the hole does not resemble the same textures of the trees in Tanaan.
