Well, I had the green honor badge (teamwork) for a little while. Just recently I noticed it's missing, also I have 60 for the teamwork. I also ran into a couple people with the same issue, and I've only seen honorable opponent ever since my badge was missing. I looked around and didn't see another form for this specific issue, so my apologies if there is one out there. Anyone know the cause of this issue is?

I'm pretty sure they reset who has the badges after a while. You need to keep up on getting teamwork and you'll get it again.
