Glitch: When I was doing the Arcade Leage match Bags Of Fun, i was getting my ass handed to me. But when i retried I went for the bag and came back to my base and saw the bot running around bag trying to get but they never got it. After seeing this it was an easy platinum. I really dont know why this happens. If you do, please tell me or add it in the article
