Thank you for finding those bugs, I'll correct them right away!The intimacy interface bug happened to me too, basely sometime when you click on an interaction either the background art jump to the foreground or the intimacy interface just disappears or fails to load (the screen just shows the intimacyBG.png), not sure if it's relevant but when it happened I was playing as female mc and had told Suzumi to call me and her by name.
Also I found a small bug in 0.17, I created a character with 18 int and 15 wis but after character creation was done the interface showed 15 int and 18 wis so seems like those two have been switched around somewhere in the code.
