Aspect of the Spider Cobweb Texture

For some reason aspect of the spider seems to apply an unusual texture overlay on these arrow filled enemies in the blood aqueducts. It removed the decent monster texture that was previously on the enemies and instead of the cobwebs rendered over that they turn into these low res minecraft enemies and the arrows turn into logs. When we went back to maps the cobwebs applied normally so I believe it is an issue with this enemy.
