[endgame]

I use PC, so don't know if this is applicable or not. Go to the Skins folders and in each individual skin's folder rename the skin.bin oldskin.bin - Then start up your game, prepare for a lengthy wait while all skins rebuild the skin.bin files and see if the problem still surfaces. Again, this is PC - but I assume the process has to be same or at least similar. If you have a doubt, check with or wait for a Mac guy to address this.
