I didn't get the 2 health points with Atigra when spending her battle exp. I also didn't get the 14 hp and 2 str points with Alaciagrace's exp.

if you wait a few minutes, does it show up? I think the pets page is cached and spending exp might not force the cache to update

Have they shown up?

I have the stats now just took longer than before which I wasn't expecting.
