This version seems to have broken a few event flags. Cassidy is impossible to take down the pet path. You get your job back and then ... nothing happens, she's just gone, set to 0 affection. Though she still retains the title of 'Pet'. This makes it impossible to progress her, Aletta or Aubrey's stories.

The 'Cassidy bursts onto the scene' changed last month (with a choice leading to Cassidy being gone forever).
This change wasn't reflected on some event's conditions, leading to events triggering when they shouldn't. I suppose you hit this case.
Fixes are already implemented but are only available on the weekly releases right now.
