In the very first campaign, map mode, raising Silaniuses army to defend a pass from the Samnites. Over several rounds the tutorial asks to raise more units, highlighting one to get. I was clicking different units, and seeing now limit, ordered a lot. Now I am in the round where I am asked to raise cavalry. But the army is full and I can't raise any. Nor I can disband anything or merge... I am completely stuck and the only way I see is to start over as there is only the autosave at this point.
