Hi there! First off, I wanted to say thanks for the mod. It's very useful since I like to change my builds around a lot.
I've also run into the "give a skill book to another party member and it gets used" issue. I bought a Boulder Bash book from Arhu and it is used after trading it.
I keep a bag in my inventory just to organize my skill books, so I pulled those out and none of them got used either. So I don't know what exactly triggers these skill books that aren't affected by the mod. I even bought a different Boulder Bash book from him, and that one got used too. But the poison dart book I bought worked fine.
It's not a huge deal, I'm just curious about what causes this issue. What makes these skill books "special?"
Edit:
Just found another Boulder Bash skill book in a chest, it also disappeared when I used it.
There is always the possibility that I missed a Skill book when I was making the changes, since I had to click through 120+ Skillbooks in the Editor. This could explain a book disappearing when used (since that's what books do normally without the mod).
I don't know what could cause Skillbooks to disappear upon being traded though.
Edit:
Hrm, the Editor refers to Boulder Bash as "BoulderDash". In my mod at least, that book (BoulderDash) is set so that it's not consumed on use, so I have no idea what's going on.
