Thats very odd... Heres a way of trouble shooting, backup, then delete the entry for both provinces from descr_strat.txt. These entries are not necessary for the game to run, the settlements should appear as barbarian villages with no population.

If the problem still persists, send me the files you edited to the.mad.toad@gmail.com
I can't promise to find the error as I'm quite busy, but I'll have a quick look.
