Is it a bug or it is just a placeholder for locking the next level of masteries and the elite skin?
Two stars should be a badge and three stars should be a badge+skin.
Check on the profile menu to see if you unlocked anything - it should be an alternative version of whatever the first badge you got from that character was. Thanks for the bug report!
No problem. ^^
The character is Val. Which badge should I look out for?
I think it is the badge with the (possibly) bald hunter - the blue person one I believe. I can verify later today once my PC finishes it’s updates.
I think it’s the mohawk alt badge. Same thing just happened to me showing just the black square.
