This is a bug I've experienced before, but it has persisted through this latest update: Sometimes my sovereign will lose the ability to move in the first round of combat unless I right-click on an enemy to trigger a move and attack. This time both of my main attackers are affected, my sovereign and my collared Umberdroth. What is particularly frustrating is that my sovereign has sweep which he cannot use until the second round of combat, when it might have saved me damage and hit more foes in the first round (and in case that wasn't clear, by first and second round, I mean his first and second turns to act).
Also, a little before this started happening, the master scout ability broke, and monsters can now attack my kingdom no problem; not sure if that would be related.
