During an Odrysian Kingdom Campaign, I occasionally received notifications about new ancillaries being obtained for my characters. Unfortunately, it seems a number of them never actually are applied to any character, and don't even appear in the available pool. Seems they may have broken triggers or something.
This is a list of the ones I've come across per character, but it's in no way a complete list. I've only tried the Odrysian Kingdom in Grand Campaign so far.
General – Zeira, Greek Turncoat, Gallic Bard, Rhomphaia, Aged Retainer, Personal Tutor, Greek Exile, Drinking Goblet
Champion – Weighted Practice Shield
Spy – Wise Woman, Witch, Courtesan, Famous Courtesan, Dancer, Acinaces
Dignitary: Pet Snake, Fortune Teller
I've seen the update post regarding what the teams are doing, and it mentions an upcoming patch for Rome II this month.
I beg you, please take a look at these. There's few things more frustrating than being reminded about something that's not working correctly throughout the length of a campaign and that someone's work making interesting ancillaries was not completed.
