It just happened to me. In my case, instead of turning blank, my location rolled back to the old value. What I did, at least one of the things I did, was logging into the website (I hadn't for a long time, lately I always visited the forum directly though /vbullet/), and then when I entered the forum again directly I was logged out from it, and when I logged back in (directly through /vbullet/) my location was reset to the old value that my website profile shows.

So it may be the website profile overwriting the forum one, whenever the famously horrible cross-profile hack comes into action. One problem though, is that the website profile does have a location, but it cannot be edited! Ha!

I remember the location in the website profile was mandatory to be filled in. Users didn't like this, so I thought it was made optional. But apparently the location entry field was removed altogether, and only the optional one in the forum (/vbullet/) remains. The problem is that the entry field was removed, but the underlying data field wasn't. I'm guessing old users have the value they had when the change was made, and new users who registered after the change have them blank.
