My current quest is to brand five War Chiefs, but as you can see I only have 4 available and they're all branded already.
How can I progress my game? Do I need to command an uruk to become the fifth war chief, if that's possible.
I am unsure of how to progress at this stage.
Each of the dominated war chiefs has a mission, which just summons them. As they're branded they just stroll up to me and I can grab them and dominate them again. Then once I've dominated them the mission just lights up again and I can repeat it.
