I've got a texture issue: when I try entering the area flooded with Radiation, my game gives me an error code which won't go away. It says "Invalid Bump-map!" for C_CONDRDL01b and C_DRDMover01b. This happened when M4-78EP was released. I tried uninstalling. Didn't work. I eventually just rage quit, and forgot about my issue, but could someone please help? Thank you.
