are you sure that it's like that on both, client and server? actually you need it only on the client but still.

@iAslana, if the textures were missing then it would be pink in places where the textures are missing.
it's surely something with wrong cords, I'm 99% sure that it has something to do with his client's maplist

if not, then try to restart your computer and then see if it changed anything, sometimes I needed to restart my pc for the changes to take place.
