They're usually safe to use in the game, but if you see a tiny glitch, you should shut down your game at least once. I've only seen 1 glitch out of my months of having the game though, so its not really common to see a mistake.
Gimme a list and I'll do it once I get home. I don't need anything in reward since I already have everything I've ever wanted.... :3
