Well thanks for information, I didn't know that before, because my friend gived me some textures and some where with cs 1.6 nonsteam. Can you tell me wich map or what texture has this issue, so I can fix it, because i have a lot of maps and a pile of textures used.
Edit: Found the source you are talking about - it is zm abyss textures.
Edit2: Huh. Every second map was this texture used. :D Fixed, I hope. If any map has still this issue, let me know what map.
