Is there any reason the Jamba features are still active while your team isn't online... or on characters that aren't part of a team?

I currently only use Jamba on my Warlock/Hunter leveling team. All of my other characters do not need it. I get messages about accepting quests and even get warnings about follow being broken (who was I following??).

In fact, I think there is an issue with the following. When I am on my main, without a team, and no one in my group... and I am on a vehicle, when I exit combat it appears as though follow strobing attempts to follow myself. (Sorry, I'm not very good at explaining things.)
