Just spotted that my Free-DC MM badge has changed to Orange. I got all excited (well, it's all relative), thinking that I had finally cracked a Sub25M I've been working towards that would have taken me there, but no! I haven't.
I appear to only have the 49 MM's types that I had last week when I feel fairly sure that I was green.

Unless I have somehow tripped another of those mysterious hidden ones that you don't see until you get more than one!!!!!
