PS4 Automatic Tier 2s Suddenly Unlocked. GLITCH?


I’ve unlocked all three tiers of my favorite classes. As expected, all but the first were initially locked. Moments ago, I decided to try out two other classes that I had hardly even touched (Assault and Support). To my surprise, both 2nd tier characters (Hyde and Bucket) were unlocked and fully playable/upgradable. Turtle Rock, did I achieve something that allowed this to happen or is this a glitch?
