[Bug] "Learn All" words button (execution) is very slow

[leeterry]

Description

After finally getting it to work (see my post in the other bug report). I loaded my save and attempted to edit my languages/milestones (hoping to get rid of the spam messages). However, the editor froze when I clocked the learn all button and became unresponsive for a few seconds. After that time had passed and it started working again nothing had changed despite my pressing the button and clicking each option to learn the words manually had the same result.

The current implementation isn't ideal. The "Learn all" just unlocks each as it would when you manually unlock it which is quiet heavy. For each word it first has to find and update the actual value and then it has to find and update the WORDS_LEARNT stats by counting all for the global number and then counting again for the race.
For examaple there are over 900 words for the Gek and just takes it time to do this for all of them. Would be better to just update the value and count once afterwards (or just set it to the total no of words as we know that number).

Beside that it does what it should. I just tested it and all checkbox were set and after saving and restarting NN all words were still marked as unlocked.

I'll keep this open as remainder to improve it in the future ;)

Hello there!
"Learn all" button currently (at curse exp version) completely hangs the app. Its constantly using precisely 10% of my CPU and 771.5 MB of RAM and nothing happens. No disk activity there. The app does not respond.
