0.8a status. After experimenting with the chances of unlocking an H scene (peeping), I went through at least 30 days in that same spot and nothing. That save file is 100% complete by the way. I eventually unlocked it by making a New Game + and got it the first trey and then went back to my old file and instantly got it. Not sure if bug or I was super unlucky.
There seems to be an HP inconsistency bug. Doing the Arachne quest drained quite a bit of HP (I had low equipment are the time), but afterwards and going to regular hunt or a different quest treats my HP as full, and then doing another quest or continuing the Arachne quest displays the original low HP.
The skill point reset item is a pleasure in case someone decides to not put any skill points on the central skill, required to start the chain of side quests. On the other hand, this also breaks the game as using that potion after that required spot means putting all points in attack to curb stomp battles easily. But hey, it was enjoyable.
