12 unown, which of 9 from event.
Letters outside the unown events:
- x; was at a raid way before the unown events began when someone called an unown and I had the opprtunity to drive with someone and catch my first ever unown
- j; someone informed me and offered me the opportunity to go with him
- v; the only one I caught myself when someone informed the group in the middle of the night
Unfortunately, I'm pretty sure that others got their information by mapping.
