Yeap, if you aren't using an auto-seduction gem (in v0.2) the chance is exactly 50%. I'll double check it later, but a quick glance shows nothing wrong.
As for the loading problem, I'm not entirely sure that it's a hardware issue, but I only managed to reproduce it only on the low-end virtual device. Not sure why it pops up in a zone without extensive logic block, animations or a big map...
Oh, and good luck with the surgery!
