I have the plugin in the folder but no HP1 girls are showing up for some reason, Kyu constantly has the blanked out portrait so I think it kinda works, but I dunno why I'm not seeing any of the HP1 girls. Also it lets me take the HP2 girls on dates to locations from the previous game but it's broken into tiles that are jumble around in the background

I had the same issue with the Kyu portrait and tiled backgrounds before I added HPModTweaks. That fixed it for me.
I'm not getting the HP1 girls either, just the locations and original sprites for Kyu/Lola/Jessie. I also have a separate issue, where when I date a pair that just have the new 'attracted' status rather than 'attracted and horny', it'll play the bonus round dialogue at the end, then redirect me to the girl finder, and I'll have a broken grid stuck in the middle of my screen from then on until I restart the game. Just now, it actually broke my save file. :( Seems to be an issue with them not being in their designated bonus round locations?
Edit: Removing and readding this mod seems to have fixed the file. Yay!
