Yup. I checked into this to see just how much corruption you could get at the casino, and it's unlimited--you can actually die from corruption during a single turn if you're gambling. Now let's say you're going to risk it and you're holding down the space bar... "Game over."
Yeah, I think we need an automatic y/n thing for new corruptions, whether or not they occur at the casino. How often have you messed up your wands or potions because you got a new corruption and didn't notice?
