Savage Moon? The title's creators hear your cries -- producer Simon Livesey recently responded to complaints from players whose copies of the game have been rendered unplayable by the patch, and explained that the error is only hitting people who downloaded the trial version of the game, then later unlocked the full version.
FluffyLogic is hard at work to fix the game-wrecking bug -- fortunately, Livesey mentioned an easy workaround for the error: Simply delete the game, download the trial version again, and unlock it. There, see? That wasn't so bad. You can now return to your regularly scheduled insect-alien genocide.
