Not a bug! See following post.

Summary of bug:
Relevant cat: "Heart"
Today (12-25-23) I had Heart work the Student job, and received the text:
"Heart's finesse improved! Heart used 3 vials of Black Ink to create the following items:"
(They rolled an 11 and got 2 science practices and 1 black ink).
However, when I checked Heart's page, their finesse (or at least the displayed number) had not increased. When I got them from Nestor they had the stats (w/o mayor/trinket bonuses):
Strength: 8
Agility: 8
Health: 8
Finesse: 6
Cleverness: 6
Perception: 9
Luck: 9
Which I noted down in their bio. Their base cleverness has since increased by 1 due to the student job a while back, but unless my notes are wrong, the supposed increase in finesse stated on the gather resources page today didn't actually happen.

So either the text on the gather page was falsely displayed because the kitten wasn't supposed to get an increase or the kitten was supposed to get an increase and that never happened (or my notes are wrong).

Steps to reproduce:
Have a kitten randomly get the finesse increase as student.

@Air
When a stat improves, it's their final adult stat
Due to the fact that adolescent and younger cats only have a percentage of their adult stats, their current stats might not show an increase.

@Verm
Thank you! I had thought that the stat increases from students were applied immediately, not grouped in with the total adult stats, this makes sense now.

moving to help as it's not a bug!
