No warlord after completing stables upgrade

I finished my upgrade to the stables that should let me do missions, and I can make teams and such in the stables, but the Warlord isn’t anywhere in my castle. I’ve tried leaving the castle again, restarting the game, and even checked the table to make sure the upgrade was completed. Is there something else I need to do or am I just never going to be able to do those?

Missions are unlocked with a different upgrade than the stables upgrade. You’ll unlock them a bit later on.
