It's not "losing choice" when you build a castle. Not by a long shot.

With a castle:
Research and be safe.

Without a castle:
Research and fight.

Sometimes one is better than the other. Admittedly, there should be a command "research and fight for province", just like there should be a "preach and fight for province", just like there should be a "preach and hide". In general, there should be more commands than there are, you should have more choices than you do.

But right now, the castle does not give you "less options", it gives you "different options". That's weird, and it should give you "additional options" if there are going to be any differences at all. But that's a separate thing.

Possibly "Hide/Defend Castle/Fight For Province" should be a separately togglable order completely distinct from the basic orders you are giving people.
