3.80 (beta) Retting improves unarmed skill

[Galgana]

My character's unarmed skill went from 40% to 43% after I soaked 100 units of a plant.

That doesn't seem right to me because the retting action falls under the textilecraft menu. Is this intentional?
I can think of a similar example where a weapon skill improves outside of combat, e.g. flail skill when threshing from the agriculture menu.

Did you help someone who was lost in the forest?  If you did, you probably got the 3% rise from him.  The rise is not implemented until the next time you use the skill, so you may have helped him months ago and then kicked a bird to death or something, which would then give you the 3% rise in unarmed.

Checked the code, and there was no such conflict/issue to be found there.

Could this be that the increase happened earlier, for some other reason?
Bert Preast's theory is one plausible explanation.

I never completed any quests on this save file, as this was a freshly generated character I was using to test flora edits.

Okay. Then it's quite puzzling issue. Codewise there's no conflicts to be found, and with a few quick test I couldn't reproduce.
Maybe an overflow somewhere that affected the unarmed skill is my best guess. Please follow-up if you notice it again.
