Edited the title of the thread, because I found more:
3) The Merc Peltastai don't have updated unit cards yet
4) The Merc Leuce Epos (merc Gallic light cavalry) have a charge bonus of... 1
5) The hydragogion (sometimes) misses a 2D building card when selecting it for building. Though once selected it is there. (Yes this an old one.)
