I just started my first game after going through the campaign. For the first couple turns nothing was wrong, but now my sovereign wont go into tactical combat, every time I send him to attack something I don't even get the combat window asking me what I want to do, it autoresolves itself in a suboptimal manner, wasting spells when there was no need to. Is this normal, how can I get tactical combat back?

TLDR: My sovereign's fights keep autoresolving without giving me a choice, can it be fixed?
