Hello, i had weird issue. So i made zero hour normal after that heroic got outbreak and catalyst also 20% on siva, but then i sent this gun to my hunter and catalyst with progress was gone. I decided to send it back to titan but catalyst wasn't there anyway so i played again zero hour heroic and get catalyst with 20% progress but i should have 40%. Somehow my progress got reset. Anybody can help with that? Also second character didn't receive option to play heroic if it was unlocked before on other character.
You’ve only beat zero hour (heroic) 1 time. Thus, 20% is normal for you.
You can only do Outbreak on the character that discovers the quest at the moment.
