One big thing that is missing in Bug section:
Damaged groups of troops going to 1 after save and load
This is really serious issue, since you can get injured grouped unit transformed to single unit, after saving and reloading.
I mean, it can really mess up your army. I expect this to be fixed ASAP. It's too big issue to get tolerated for long time.
One minor thing:
Some units still have combat speed of 1, including several starting sovereigns, campaign heroes and sentinels from warlord trait. By looking at XML data files, it appears all those units affected never had combat stat speed set at all, so game defaults it to 1.0 for them.
And for the last, link to bug fixing mode. Gives ideas what else could be bugged, but is not fixed yet:
