I give up . After pouring so much effort into Chapters 1-18, I could accept that Chapter 19 reset all my progress. But now I'm stuck at 25/86 in Chapter 19 with just '7, 17, 18' as clues - totally impossible to progress. I have no choice but to drop it.
Seems like there's a few bugs in ch19 unfortunately, best to skip ahead.
If you open the console you can try this.
EVENTS[1].SetDone()
Most likely this one is enough. Close the console and skip ahead one day, then one hour and you should be at level 2 and be able to progress.
(These are the other trigger requirements, but I think you have them if you were at 24 or 25 /86 since thats where I was stuck as well

)
EVENTS[69].SetDone()
EVENTS[0].SetDone()
EVENTS[34].SetDone()
EVENTS[27].SetDone()
EVENTS[6}.SetDone()
EVENTS[52].SetDone()
EVENTS[77].SetDone()
EVENTS[63].SetDone()
I think EVENT 1 is supposed to be in the bathroom to enable level1_2 active, unfortunately, the bathroom that sets EVENT 1 to DONE requires you to be on level1_2 already... so..
You'll run into another block on level 2 ch 19 with the same bug as above, where EVENTS[2] has been added as a requirement to advance to 1_3 despite it being "hidden" as an objective UNTIL you complete it.
"09:00 Wait for Thea at the bathroom door"
Same issue is there for level 3, 4 and 5. with EVENTS 3, 4, 5.
