I noticed a bug (heh) with the Vebbeddinner sex scenes. I'm playing as a Greater Slime, and if I have a vagina, I can't select either of the options. If I use Reshape (mid) to switch to a penis, then I'm able to select both of them. This is true for when losing the fight against her, and when talking to her after winning the fight. I don't know if this also affects the other playable races.
I also noticed that the portraits for both male and female spiders seem to be broken.
