Reading the rules it seem clear that the virtue Apt Student apply only when someone teach to you.
Using metacreator (last release) to study summae it ad the +5 bonus alogside the book learner bonus for a total of +8 to the study total!
is it an error of the program or, more unlikely, i misinterpreted the rulebook?
ah - 'fraid not.
Actually you are wrong and the program is right:
Book Learner - when studying from books treat them as if they were 3 Quality higher
Apt Student- when being taught by someone else, add 5 to your Advancement Total
You have mis-read this, and failed to note the division: Book Learner applies if and only if you study from a Book (not when being Taught, Trained, Practicing or using Exposure)
Apt Student applies if and only if another character uses Teaching or Training to teach your student.
Umm, he was quoting the metacreator. So he is not wrong or right in that statement. The program is wrong that it does add +5 when reading a summa.
I noticed the same thing in the creator. Another bug that drives me crazy is the ability/age limit... if you increase an ability above your age limit, the program drops it back down despite the character being "established" and not subject to age limits in thier abilities as a starting character would be...
