And I've noticed sth else now that's kind of weird.
At the ends of fights Piloo's INT values behave strangely. They increase and decrease arbitrarily. For instance (on her current level), before a fight she has INT 408. After the fight I get this:
Now her stats will indeed show 410.
After the next fight it will get back to the previous value.
There are never shown any statuses on her, nothing changes. Only her INT value jumps up and down just like that.
