Is that new? Because in the past, all six books were available in the game setup area, when you make a sovereign. In fact, I still have a saved sovereign from an earlier version of EWoM that has all six books to start.
New as of 1.06.
weird. I've been using my same old sovereign, and he still has the summoning book attached to him.
Probably not so strange if you created a custom soverign pre 1.06, I don't think it validates the soverign every game, they just removed the book from the creator not from the game. So if you already had it on a custom soverign I imagine it would remain.
