Alrighty, starting from the top:
There was (I believe it's been fixed in my newest (unreleased) version) a set of commands issued that Peter would walk around the room at night during the, uh, "visit"; when you wake up in the morning, he's still moving because the movement event was created to show him walking in place.
Like I said, should be fixed in the upcoming version.

The amount shouldn't go up, but even if it does, it won't actually change anything - it's probably just a scripting error and I'll check it out. Thanks for the heads-up.
#3:
The text messages are static - they don't change, even after she's completely enthralled to you. I figured I'd go in and create a few more for variety's sake, and I'll probably need to ask Chilly how to randomize certain things because I can't figure it out. If you can and/or know how, please let me know and I'll write up a bunch!

That shouldn't be happening; it's probably because the game assumes that A) you've spoken to Dizzy, and B) don't already have max rep with her and/or your sister already. If you've spoken to Dizzy and maxed her out, along with your sister, you'll hit that window every time; I'll take a look at it anyway, see what's going on there.
Thanks for the replies, all - Mom is (more or less) done, I'm pretty much complete with everybody bar the Park Milfs, Kim, and I think Donna. Newish update as soon as I can find a stable internet connection and get more of these bugs dealt with.
