Thanks for figuring the province #53 volcano issue out. I've changed the terrain mask as suggested.
I thought I made sure everything was normal with the provinces using the map editor, but province #53 just showed "large province, border mountains" checked.
The random generator must have decided on that mask because of the volcano. The only doc I saw for map editing is the pdf in the docs directory, and it doesn't have information on specific terrain bits.
Anyway, if you like, please download a new copy of the map from:

Edit: I think everyone will have to upload their pretenders again, sorry! But please wait until thejeff checks the map.
