It appears that the Jjarro Wall textures (except Terminals, switches, and recharge stations) are not being loaded, not sure if this is just me or if anyone else has this is issue.

Jjarro textures aside this is the best texture replacement plugin available. It adds a very different feel to the game while staying true to Bungies original textures and makes me want to play both of Marathon's sequels start to finish once again.
