Have you had any luck progressing?
I've been playing this game for years so I can try and help - this may be a silly question but did you pick up the phone and arrange to meet Cassidy at the office?
Hey! i did actually, the problem was brees visit workplace (ntr) events first step was overlapping and forcing the event to restart softlocking the game, i found an old save and didnt progress with bree untill the work / cassidy events were fully done. only discovered it thaks to a loot of trial and error
