Focusing on a trait is still somewhat broken, and when I did it it made a bunch of errors pop up, like this:
As you sleep, you let your mind drift to more feminine thoughts an you recall the feelings of your feminine body. Allowing yourself to focus on being more Feminine.

I was able to fix this (at least for the trait I tested) by using find-replace to change all ">><set" to ">><<set", which suggests that the problem is mismatched angle brackets.
I also had a problem earlier where I couldn't focus a trait at all even after unlocking it, which was solved with a similar find-replace to fix mismatched angle brackets.
Also, if you go to the "focus on a trait" menu and then choose to just go to sleep instead, it doesn't advance the day properly and you're stuck at 6pm.
Edit: for reference, this was observed on the current free version, 0.10.2
edit 2: itch.io automatically changes the left and right angle bracket character codes (lt; and gt;) to their character equivalents when making a comment.
