Got bombarded with achievements.

So between 10:35 and 10:54, I was given 5 different achievements for completing missions or multiplayer games, also looking through, I’ve been given an achievement for playing “a multiplayer or co-op game at least 3 months after your first game.”. Anyone else getting weird things like this?
