I understand that reading an advanced book at too low a level will give a confused moodlet. I was likely not noticing it before.
However, I'm observing seeing no skill bar / advancement when say level 1-3 and reading the first book.
I just tried to read book 3 of fitness at skill 9 and got nothing but bored.
I have read book 1 of logic at level 3 and had no skill bar.
I consistently use the skills to skill up but sometimes when bored as a player to switch it up I like to read rather than do something else infinitely and the books are not all working consistently or granting skill experience consistently.
I still haven't figured out the 'recipe' books; no recipes learned from them, just got bored, did get skill up reading a cooking one on another sim at a lower level but no apparent recipes learned.
I also seem to have 'lost' the garden salad recipe along the way, unless it's time of day sensitive, but none of the other recipes seem to be.
