Arko: I mentioned last time that the Zoroastrians have lost their hexagon CoA shield and use a circle like the Muslims, and you mentioned looking into it for the next version of Armoiries. However, the latest version still has circular Zoroastrian CoA frames. I've tried fiddling with it myself, but I don't know how to force the game into using frame_zoroastrian.dds.
edit: also, the Abbasid CoA should really be added into the Muslim group in coats_of_arms.txt and a religion=sunni or whatever should be used in their section in dynasties.txt so that they don't use the Western frame, which is really jarring.
edit2: Actually, that seems to go for a lot of places with defined CoA -- the Seljuks, a few later Indian titles, etc. the religion=[whatever] bit should help them avoid getting Christian frames. Unfortunately, I don't know how that'll be possible to attain without modifying landed_titles so maybe this is a PB issue?
edit3: fixed the Zoroastrians myself! You probably already this since you're the one who originally figured this out in the first place, but just in case: in coats_of_arms.txt, the Zoroastrians need "coa_plain_muslim:1" to be switched to "coa_plain_zoroastrian:1"
