Corvus not gaining persistent charge against evade champ - Mission 4
Originally I thought Corvus gained a mission just for fighting and beating an evade or auto-block champ but realized you had to finish the fight with a heavy or special attack. Just used Corvus in the daily science quest and after Spider-Man (Miles Morales) evaded me I stunned him and used a heavy attack which finished the fight, then went to the next match up and Corvus still had 0 persistent charges.
Is this a known bug, something new or am I missing something?
