Present 1 never goes gold
I'm having an issue where the Present1 skill isn't going gold despite me practicing it endlessly. I feel like I'll never forget "I like chocolate" because I've had to do it so many times.
This seems to be a long-standing bug in the underlying Duo system. The answer is apparently to redo the section rather than to try and 'strengthen' it.
I've had this issue for a while now. I just gave up and now I leave it alone.
