Greetings! I'm playing a large map, and thus trying to end things more quickly by winning through an alternate route. I researched the spell of making, but it's greyed out so I can't cast it (saying I need 4 influence, which I'm not sure what it is, though it has a cup like faction prestige and says "4", while I have 13 faction prestige). I turned to the master quest, and a couple of steps in I need to find the Free Riders. Their compound spawned on a wall surrounding a wildland:

I can go all around it, but my armies cannot step on that tile. It's a wall, right?
Fun fact: this wildland's quest was to be subjugated and build a city inside. I would love to (lots of great resources, including three shards!) except even after clearing the area my pioneers are told "can't build in someone else's influence"... d'oh!
I must add, however, that I'm playing a LOT of this beta and thoroughly enjoying myself, and am amazed to learn that there's a LOT of content yet to go into the game. Thumbs up, Stardock!
