I had a mission where I had to accompany someone on an attack, and I just sat there with everyone else accompanying him, and him just waiting for me to do it, and I couldn't figure out how to do it. So eventually they just all left.
Plus can you accompany a group or follow a group that you happen to pass by? If so, how?
as a human player all you do is manually follow them, the computer counts/lords/whatever can actually be asked to follow through the i have a task for you option. The game assumes you know what actions you are taking so it dosent show you are following someone is how i think of it.
