Dunno if this is one of the bugs you've caught yet, but i accidentally clipped through the wall at the pet shop and into the gym to do squats by spamming F in the pet shop. I immediately cancelled the workout, but now whenever I inflate anyone, I start working out Ayume's ass as well as inflating the person. Her butt is now so big that the clap of her asscheeks keeps alerting the residents whenever I try to sneak up and inflate them (or, in a non-meme way, doing this allowed me to bypass the intended max butt size and now Ayume's butt is massive and looks horribly disfigured)
