Time for a real thing that has not already been fixed in the latest version this time
(might have already been reported but did not see it), basically I noticed while playing the Lysimachids (this game may result in a post in post your empire thread I hope, only at 474 at the moment though) that many of the provinces of Kassandros little kingdom had the standard rebel flag among the cores, looked at it and found out why, the history files add cores for cAS rather then CAS, it is appearantly enough for that to happen (and hard to notice, took me quite some time to do it, even had to look in the savegame to find out when those cores (for country --- it seems) had been added and then I could finally actually see it in the history file).
