After a little bit of testing, I tried it on an old laptop (almost 7 years old, now), an external HD, a built in new (year old) SSD and another storage drive. Said laptop is working with Windows 8.1 and my main computer is working with Windows 10. The only consistent crash I can find is when I skip completely from NEW GAME all the way to the first sex scene with Lili (after murdering the bandits). This situation crashes about 75% of the time, I would say. If not, it would crash at random places.vernaugh Hmmm that is not good, crashing while reading... I'll take a look in the future, for me it does not do it, is your computer using hard drive or SSD and is it old or new
I transfered my save from chapter 1-9 and I managed to get up until the scene where we are given a dream scene by Lili. I can only assume that it's a drawn CG scene because the game crashed as soon as Lili mentioned something to the tune of 'enjoy yourself'. That's as much as I've tested so far, I'm afraid!
Edit: Ah, yes, forgot to mention on my W10 PC, I also tried the game with Admin privs and also Windows 8 compatibility. I can get further and its how I got to the Lili-dream-conquest scene but, ultimately, the game crashes still.
