Hmm, can't really tell why the snooping event did get skipped for you, but it could be because you seem to reset time/days a lot...
Did you try to play the game like the dev intended without resetting the days all the time to see if the bug with the snooping event is reproduceable?
Thank you very much for your test. The event is a bit complicated, so let me explain.
I have been using Time Set Mod for games since a long time ago, including Route1, 2, and 3 in the saved files I uploaded, and I have been using them all the time. Except for Sam Harem, there is no problem with any event, but only Route3 has problems.
Route3 will start with Sam Harem first, because I knew the existence of the friendly harem at 23.7.0c, but I am not sure if the relationship with Sam will be affected. During Route2, there was an incident in which Sam suddenly asked whether to back down during the Emma incident. This did not appear on Route1, so it was finally decided to go to Sam's harem this round.
The possibility I can think of is that I controlled Minami Harem's harem immediately after Sam Harem's harem. During the snooping event, I happened to trigger MC, Bree, Sasha, Sam's Threesome and Foursome.
In addition, there are already other victims, #34, bobr12 of 147. I'm not sure if he uses ATC, but from the number of days he played, it should be more than normal for me
I know your doubts. In the mid-term, the use of TSM or ATC has slowed down, especially when many things need to wait for the process, the frequency of ATC use has dropped significantly, and the use is more of Wait, Work, and Sleep in normal games.
And I still won't give up using ATC. ATC is very convenient when I want to help find out the problem. I don't know how to decode, so I can only use the save provided by them and run it in the game. Or restart, or Find my old save to see if there is anything that can test this event.
