I Just got 20 achievments for like 540 at the post game lobby of the first match I played today is it a patch for the achievment I shouldve got prior or a glitch because the map was Exile and all the achievements were for DLC.
Correct. Most of those achievements were glitched for everyone (permanently locked) so 343 unlocked them a couple hours ago.
Qalright thanks.
I was so confused when that happened, because my I froze in the war games lobby. Then when I rebooted I had 23 DLC only achievements. Don’t really care so much for cheevo’s but it’s nice to know I unlocked them.
Oh my goodness, the easiest 16 achievements I ever got.

Glad you eventually got those achievements.
