1: 0.4.3b
2: MacOSX
3: After combat, raping anyone who has been captured decreases mana by the amount it said it should increase (if it says my mana increased by 4, it actually decreases it by 4. If my mana is currently at 0, nothing occurs)
I've tried this with a few different characters now with the same result in different save files, so these results appear to persist throughout playthroughs.
Otherwise, it's been a real great game so far. Great job!
