What's the big green map pin all about?

I have a massive green map pin appear next to one of the thread titles. Is this a new thing to point out local threads?

It sure is, but it shouldn't be MASSIVE Jin can you post a screenshot please?

Ok maybe it isnt as massive as I thought looking back but it certainly stood out!
