Shield Wall + Ahn's Citadel + Branching Fissures II overwrites some wall segments

When you support shield wall with Ahn's Citadel to allow the wall to be created along a fissure, and then support that with branching fissures to allow the fissures to branch 2 times, the branching fissures do not correctly branch. They either seem to draw/render directly on top of the initial fissure from Ahn's Citadel or they branch off close to the player's attack location and seem to overwrite the second branch's initial wall segment. It sort of looks like the the second fissure spirals back on top of itself - its not easy to explain.

It just doesn't seem as though these branches are being created in an intended way.
