They dont have testers and i am not joking. Ill give you and example: bretonian damsels were given troth system ... it didnt worked from day one when they had added it which means noone have actually checked is it working. Then two patches in a row they said they fixed it... guess what... still same as it was when they have added it.

I wish they just added an auto resolve function on quest battles. Really slows the game down when you have to wait for everyone in the campaign to grind their lords unique items.

​Allied units entered the battlefield, they clustered together and did nothing - this is an old and well-known bug.

This bug was introduced in patch 3.0 or 3.1 (maybe earlier, been so long, I can't remember precisely) and I've seen a lot of people complaining about this and it's been reported here several times as well. 

Now, more than 1 year later, it's still there
