Not sure if you've fixed it already, but as of revision 438 (svn), the dynamic names are kind of screwed up- The Mauryans and Qin don't become the Sunga Empire and Nan Yue, respectively, when they respawn, and the Han becomes the Kingdom of Wu at like 100 BC or so (forgot the date).
There must be more to it. Only rebel culture - still losemade the Nan Yue province a bit smaller so Changsha's fat cross does not enter it.
