Challenge Battle not Triggered

Hi @xrmiao4,

I've checked with the team and this was actually working as intended. A challenge battle for unknown units will only trigger now when you are below the level of the unit your opponent is using. Since you were level 46 and Scarabs unlock at level 44, you already unlocked them level-wise, despite you haven't received them yet. That was the reason why it wasn't a challenge battle. Would your opponent have used Avatars for example, then it would have been a challenge battle. I hope this makes sense.
