I have the downloaded version you buy directly from the Official Website for Disciple 3.

It seems that my first mission for Legion of the Damned is Bugged.

I reached the glowing marker for the City you have to reclaim but nothing seems to happen.

I restarted the map 3 times and each time the same thing happened.

Am I missing something?

Also I just noticed that the entire map has no creatures on it.

So something is definitely wrong. Did I get a bad download? Is there a patch to fix it?

It's obviously bugged if there are no creatures on the map. You could try deleting all your saves and restarting the Legions campaign. When you reach the city, it should turn into a Legions capital and then you would get an objective to capture five sources of fire mana.

Yeah, I reinstalled and deleted all my saves, and it seems to work now.
