On the way to Alberta there was an obelisk the party stopped to read and stepped into a "hex" circle. There was a comment about "he does exist" or something like that. I assume that was refering to a "horse" man riding some weird beast nearby.
But I cannot interact with the NPC even when stepping in front and hitting an action key. What's up with this encounter? Is this a later game issue that will resolve itself? No one has mentioned this yet so it makes me wonder what's up.
