Whenever i got sorted into match when im suposed to take over a bot who happens to be a character not yet unlocked, the abilities i use doesnt count towards character mastery. I don’t know wchich one is bug? Taking over locked character or the fact that character matery is not counted.
Character mastery is not unlocked for characters you swap in to.
Neither of these is a bug.
You are able to take over as characters that you haven’t unlocked if matchmaking places you there. You can also be put in DLC characters that you don’t own this way. You can’t control if this happens or not, but it could happen. Because you don’t have that character unlocked, however, you do not gain in progression. You need to unlock the character for the progression to count.
