My apologies if this has been resolved, but did you happen to notice any errors when you were downloading the server files ingame? I can't see why else this would happen if that's not the case.
Regardless I've uploaded my version of the server cache files in a .rar archive for you. Give it a try and if it's still an issue, try to PM Earl on the forum here if you haven't already.
btw it's a fresh server cache install from today, I checked Oakridge afterwards and it looks perfectly fine to me! just unpack it and put the folder in your samp/cache. best of luck
