Just did a pvp conquest challenge with 2 other guild mates, the goal is to get a personal score of 300 or over across all teammates & you need 3 or more people to participate – Well we achieved that easily and won but yet we still had the challenge timer going as if we hadn’t even pvp’d. We assumed once the timer counted down to finish, maybe then we’d get what we needed but no, we still got nothing.
So I’ll go ahead and assume this is a bug, since we met all requirements if not above.
