The Fist of the North Star achievement doesn't have to do with booping the catgirl; it has something to do with Pixie.
The mod reads various story variables to tell if the player has obtained an achievement, so basically the check achievements button checks the entire history of your save not just what you've done with the mod.
(String Theory has something to do with Fawn~)
I figured out what the Fist of the North Star is~ Thanks!
Also I think I might've found a bug - Back when your reply to my comment didn't exist, I loaded up a new save file (max stats and money, if that helps) to try to find out what the Fist achievement was - and I found out what string theory is (Res. check 110 ;) ) - I didn't get the achievement from that. I just checked the Fist one on my new save and it works fine, and Fawn's replay doesn't work so I can't replicate String Theory's conditions again on that save.
Also also, another interesting thing - a bit after Fawn's harsher play (String theory attempt), when I slept (at the place where you can pay 5C for a homeless guy to guard you) I got a strange dream - My chara was apparently on a beach with a chastity cage trying to touch themselves - they remembered they put the key at the resort they were staying at - and a weird sort of half image with what appeared to be a version of Fawn's basic features flashed on screen for a frame before the dream ended. Is this a preview of the upcoming dreams functionality? Or is this some extra rare occurrence from the base game? I can't find anything on the wiki, so it might be worth investigating if this is something new. If I can replicate it and record it, I might edit this comment with the screenshots.
It does seem like the string theory achievement broke when I went to port the mod to the latest version.
As for the dream it is from the mod. It looks like I forgot to disable it after I was done testing. That dream sequence probably won't be done for a bit, but the first dream will be in the next update.
I'm going to try to get a bug fix out in a few days (or tomorrow if the string theory problem is simple to fix).
Thanks for reporting :)
