In v1.1.0 of the game, there is a bug when ending the ero part where you will get stuck at a black screen or not transition at all. This bug seems to happen WAY more when using this patch. I contacted the dev about it and they confirmed the bug. This bug will be most likely fixed in the next version of the game. For now, it is what it is. The only thing I believe you lose is any stats gained during that ero session. There is actually a work around though that just makes it slightly less inconvenient since you don’t have to close the game.
At the black screen or whatever screen you get stuck at, the UI is still there, just invisible. You can click the bottom right corner to try to hit the “Restart” button. You’ll hear a sound when you click it and then the only thing you have to do now is spam click where the “Yes” button would be in the center of the screen. If you do it right, the ero part will restart and you can try to leave the ero part again. Alternatively, you can switch to the game to Japanese temporarily and try to leave the ero part. The bug will happen much less often this way. Again, nothing I can do here. It’s up to the dev at this point. I’ll try to update this patch as fast as I can when the bug gets fixed. There may also be other bugs that may occur when using this patch. At the moment, I’m not aware of anything game breaking.
