Some textures don't seem to dump?

[Gsprfdude]

   Hey so I'm currently working on a texture pack, it's chugging along pretty well but a problem I'm noticing is that some textures seem to not dump. These are textures that I see almost constantly across many different areas of the game so it's very noticeable and I really can't tell why they won't dump.

   Any ideas/solutions? I'm probably missing something really obvious.
