idk but Zazmio mentioned having the same issue and he had to seize and cede the castle multiple times to get it to work. I'm pretty certain you have to move the garrison out of the way to seize it. then you'd try ceding it, wait a while and repeat if it doesn't stick. put the garrison back there after it's worked.
What do you think of as the ideal garrison unit build? It's very different to the ideal main party build.
I had by far the most trouble taking down archers when fighting Kronk's garrisons. mages, priests and Warriors seem to be too easy to take out by a determined player. when attacking player garrisons, I focus-fired everyone on characters in that order (warrior, mage, priest), while hitting the archers with entangles. The offensive classes go down so quickly that they hardly get a chance to inflict any damage.
Defense is weaker than offense in this game. Archers serve the best chance of slowing down an attacker. They drag the battle out. And remember, it's the attacker who spends the effort and turns for the battle, not the defender. So dragging out the battle makes great sense for the defender.
So my current go-to build is an archer. 25 CON, 10 Int, the rest in Agility. 3 skill points in mettalurgy, 3 in fletching, the rest in beserker. Get plate armor. The encumberance doesn't matter at all since they won't be moving around. Pump 2-3 levels of armor upgrades in there too, so they should have armor 30+ as well as any AGI bonuses.
Similar, but some of my garrisons are catch as catch can (to save money, I will hire warm bodies and try to make them work). I also tend to put at least one priest per garrison.
When I'm flush, I train elven archers(they are perfect for garrisons) and start them at 10Int, 18Agl and 18Con, level them in Con to 30 and pump the rest into AGL. Equipment...varies, I tend to pimp them out when I can with plate w/ 3-4 upgrades, but I'll also slap an indestructible leather (not on many, & mostly on the ones further away from my core area) on 'em with 4 upgrades; no much better than unbuffed plate, but no repairs needed and I've had trouble finding plate armors with decent durability.
Ive been putting 2 metalurgy and 2 fletching & as much Berserk as they have levels for on most of the characters and havent had to do much maintenance. Was thinking of bumping the metalurgy & fletching further for those with max berserk.
I also put a minimum of level 5 runes in place. When I think about it I bump them up further.
In your opinion, is the 5 con difference between our builds worth reconsidering on my part?
All the above said, I still am tempted to use warriors, since i find a fair number of indestructible melee weapons to upgrade & equip then with. I wish ranged weapons with the indestructible trait on them were a bit more common
