I will keep in them in a list that I have encountered in the game that has happened to me before or just plain site me watching it happening in front of my eyes for no reason.
1) I encountered this bug when I was equipping the harem set on one of the girls (Kay I know right go figure.) If I stayed on the around the controller logs fixing everybody up and I go back to go do something for them one of the girls (aka Kay) would glitch out of existence and unfortunately crashing my game if I decide to either like back out or If I manage do to get out of the menu and I leave an area I would be stuck in limbo loading screen.
2) This is also preceded from the bug of #1. Since I did have a save file when I barely got out and i saved which was a bad idea don't do it. I tried to go to bed and I crash. I believe, as I stated is coming from #1 from that harem set bug, It seems that it has to something with Kay within her clothing code of some sort.
3) Kay is just broken, alright I'll be honest. You go to her house to request some sexy time, and when shes doing it she phases out of existence. I don't know if just anyone else besides me but that just wack. I did encounter the "phasing out of existence" too with some of the other women's as well that you can add to the harem.
4) When your carrying Sarah is it a bug or feature if you go slow? If you do go slow, what happens if you fast or very fast? I tested and you stay the same speed.... I don't know if this a feature or a bug. Imma just say that its a feature ( ͡° ͜ʖ ͡°) (Dang if that's the case she very thicc as a young loli ( ͡° ͜ʖ ͡°))
5) There is the crack in the middle of the square that you can't walk through, however you can walk through some others as well. I don't know if you intended this a feature or a bug you just missed (aka the one where Lena and Elaine talk to the old nice lady in the middle of the town square)
6) I forgot to post this while I posting this entire thing, there is also objects that you can walk through in the mansion and or some places that don't make sense its like you phasing out of existence.
Overall, great game I love besides some random bugs here and there (I know its not perfect but we teh community are here to help for ahem "Education" ( ͡° ͜ʖ ͡°) ) I'll report more bugs if I do encounter it in the game some more. (Aka, I kinda got to the level 3 endings already. and got the harem ending as well you know the big bulge and yes this how much I dedicated to this game my latest was like almost 8 - 9 hrs and that's exploring the entire game at this stage )
This is for ver 023c btw ;) I see that you had 0.24d up so ;) just in case you encounter them
