When I played this game for the first time last year (the original jp version prior to the english translation) I had a save where I accidentally stumbled into a very glitched game state - a pretty interesting one imo, but I'm someone who's interested in glitches. Tried searching the old thread back then to see if anyone else had encountered it, with no luck, but I was too lazy to make the writeup I am now lol. Randomly remembered it now a year later when I saw they were making a new one, and I'm bored so fuck it. Unfortunately since it's been so long I can't really remember exactly what I did that led to this game state, but I think it was something to do with the fortune telling stand because that's where the save is at (and I seem to remember something about the fortune stand being what allowed it to happen when testing back then).
Essentially I did something at the fortune telling stand late at night, the save is already at 22:00 so time has stopped advancing. If I warp from there to the love hotel and enter the room inside... When I leave, suddenly the girl is with me (she was not before), and the save and map buttons are greyed out. She will have odd dialogue that she doesn't normally have when following me around, that in this context felt a vaguely unsettling lol. For example, if i tell her to change clothes she simply responds "This is what you want." and ends the dialogue. Or asking for sex she just says "No way." despite maxed relationship stats, and she won't let you dismiss her saying "Don't say lonely things." She also just says "Hehe." a lot if you chat. You also NEED to interact with her once you start, because if you try and hit the "back" button she will just say ".........." and it will reopen the interaction menu. Weird af, I don't remember any of this behavior in any other part of the game, but maybe I'm misremembering.
When you leave the love hotel and go to the next screen after that (because you can't warp without map button), walking left to load the next area will just loop the same screen over and over (a seemingly random number of loops) before *finally* loading the next map. You will also notice that time is advancing, past 22:00 somehow, even going past 24:00 hilariously. You can now wander the map freely if you want, though usual interactions with the girl don't exist right now, and the one place you CAN'T go is the shrine: the girl will stop you saying "I don't want to go." Other NPCs don't seem to exist in this weird limbo state either. Like you can go in the convenience store, but the clerk isn't there, store is totally empty.
Anyways when you finally get back home, there will be a buggy cutscene that plays where she approaches you from the house wearing pajamas (despite being with you in outdoor clothes moments before), commenting that you're home very late, and then makes some odd statements that I don't really understand the meaning of. Once that's done, the game is "normal" again and you can warp/save, except time is still advancing beyond normal limits. It can go all the way to 44:44 before it stops entirely. Kind of a weird time to stop considering time moves in 20 minute increments, and normally only goes to 22:00. Another odd thing about this state is that while the NPCs like the clerk will now exist again, the girl has seemingly despawned. She is not anywhere in the house, nor anywhere else on the map. After sleeping everything goes back to normal again, but still... How weird. Alternatively, if you go home from the start of the save without going to the love hotel, the game is totally normal, nothing odd happens unless you go to the love hotel.
I also don't know if any of this dialogue exists elsewhere in the game; I was playing in japanese back then (which I cannot read) and relying on periodic google images translations as need to progress. Now there's this english version and I assumed this bug wouldn't work anymore... but when I put this old save into it, all this same behavior still occurs. The odd dialogue is translated as well, so I'm assuming its used elsewhere in-game and I just didn't realize because I couldn't read the language. Anyone have any idea what caused this? Though I'm mostly sharing because some of you may also find it entertaining.
Here's the save if you want to try for yourself:
