Was about to die and the grace period/regenerate now prompt popped up. I opted for the grace period, the text glitched out a bit, and that was that. A little while later I tried regenerating and nothing happened, and I saw my cycle was at 0. I did still have the slowness from the grace period, though.

Would also like to mention that I tried to recreate the issue and the grace period worked as intended

@Suffril this is probably fixed in the beta, although there must be something weird going on if it's not consistent.

Fixed in Beta.
