I should have Map Mastery now, but Firebase Dagger has not updated the number of waves I've survived there consistently. I still get the credits, xp and points, but the waves don't always add to my total.
I get waves when I spawn in mid- mission and when a mission fails, but not I am on a squad that spawns in to Dagger and then extracts.
It's so bad I've given up on Dagger and am trying London, where I had only 28 waves to build on.
