Did find some pretty bad bugs of my own. Worst and foremost, reloading the day or an area either doesnt despawn npc's and then replaces them incorrectly, or it will just fuck it up after the first time. Ran into a situation where the sister was rotated incorrectly off her bed starting point and very slightly elevated. This then translated to all other movements including motion. When she tried to walk she was slightly above the ground resulting in her own moving an inch at a time every few seconds. Putting her into any sex positions also always caused her to start facing the wrong way. No amount of fuckery with teleporting to coordinates could fix it
