Oh, and the facial hair of the characters looks much more brighter since today, although i didnt change any settings!I think the brightness bar of hairs is inverted in beta-client. When I noticed it I push the button bar to exactly the opposite position than in normal cRPG to regain normal color. It seems it's not a bug.
I tried that map with your config, but reflections seemed fine. Does it happen every time for you or just that once?
