Conquering Galich from the Magyars in 867 start as a feudal lord

[Bert Macklin]

When I hover with my mouse cursor over the "build castle" button, I receive the following notification: "you must build one of each holding type first" only for this particular province. I can only build a temple and the other two buttons are grayed out. Am I missing something?

Does the county have a castle, temple and city already? Before you can build a second castle you must have one of all three types of holdings in the county.

The county has one tribal holding in this start, but it's a part of a nomad khaganate, so you have to build a castle in it in order to keep it as a feudal. But the button is grayed out.
