The crash leaves major graphical problems in windows, requiring a log-out and re-log-in to solve.
Weird and nasty - the only thing that ever did that to me was problems with the preferences file changing things in ways my graphics card didn't like, preferences should be set above data level though so can't see how that could cause any problem with provincial campaign only.

One quick test that might be worth trying; move folder to
alexander/data/world/maps/campaign/custom/....
I found BI worked better with that to get descriptions to show up, so might be where provincial campaigns are meant to work from.
