During a Pvp match when it gave you a bunch of buff cards to pick. No cards showed up for me, and once the timer for it went to 1 second. It just stayed there the whole time. Basically blocking my whole screen with a annoying tinted purple.
- Get into a Trait Ranked PvP Match
- Wait for card selection to pop up
- If this bug didn't happen try having the enemy spawn menu open while having a ton of enemies spawning in. (Because this is when the cards selection showed up for me)
