This has been going on for a long time. The tally in the widget (sidebar) for the battle quests is not working. I know it's minor but it annoys me.

Yep. I only recently put the Quests widget on my sidebar and that's definitely annoying.

I'm pretty sure this has been the case ever since they changed how battle quests work. It would be nice to have this fixed.

This happens to me too and yes it's annoying to me as well. xD I keep thinking i havent done my BQs.

Yeah, it's like a paper cut. No big deal, but it keeps annoying you.

It's pretty annoying. I think they should just remove it (and maybe Major Drills as well) from the widget and create an individual one for it, showing your current opponent and on what quest you're on (f.e. 15 / 20).
