I've run into an extremely frustrating bug. I am running Spore on a mac pro (latest version of OS X, all the updates installed, 2.8 gHz x 8, 8 gig RAM) with an Nvidia GeForce 8800 GT. The problem is extremely reproducible. Whenever one of my colonies is under attack I am fine. However, if the alien race manages to destroy it, the game crashes. I think it may be linked to "surrendering" the planet to the alien race. A perusal of my system logs reveals the following error message: Sep 14 11:51:16 mac-pro [0x0-0x70070].com.transgaming.spore: err:SDL:SDL_DoQuit(): destroying mutex I would definitely appreciate some suggestions as how to clear this problem up. These bugs have rendered my current save nearly unplayable. I basically have no leeway to venture anywhere because if I do and my colony gets under attack, I need to fight them off before I lose the colony, otherwise my game crashes.
