overthrow the king quest

[babis8142]

Hi all, for starters I'm sorry if there is a thread like that already but i didn't find it; the forum is so chaotic!
I have taken the quest to everthrow the King Graveth ruler of Kingdom of Rhodoks for the first time. I started by asking every "blue" lord to come with me and join my cause and fighting those who refused. Eventually i conquered all cities of Rhodoks and a message said that the Kingdom of Rhodoks is now ruled by Lord Castor of Veluca but the quest is still not done. Does anybody know what it takes to complete it?

I think maybe it's because i didn't gave Veluca to Lord Castor

The game version is 1011. I am experienced M&B player (i have been playing from 750) so if it is something simple say it smoothly (so that i won't have a heart attack or something  )

To my knowledge this is a bug that just happens sometimes.
There is no way to get around it unless you reload from before your victory and hope that the quest closes this time.
The good news is that this open quest does not hinder you in any way.

As you guessed this question has been asked several times but I'm not sure if any of the other threads includes a solution.
