Bah, accidentally deleted the GP post. For anyone following along it was about the day 137+ Tanya training room, and 139+ Breeding Lab events on the good path. They actually come after the day 141 event.
Thanks @Jamleng Games. I ended up reading the script file and discovered this too. I remember a couple other events that were allowed to run out of order and played weird because of it; top of mind when saving Elsa from the bullies I pulled a gun, but at the time I didn't have one; it was probably meant to be blocked by getting the second gun. That was on 1.0.0 so you may have fixed it since.
