I have been using Hero Lab to plan out my characters for a while now, and I'm in the process of creating one right now. For some reason, when I tick the box that restricts the options to Pathfinder Society Core Campaign, I cannot choose a deity for my character to worship. It says 'This selection is not available for Pathfinder Society Core Campaign characters'.
Is there a reason for this? It doesn't allow deities for clerics either, which I find weird. Since deities are in the Core Rulebook, I can't see why they are not allowed. The only reason that perhaps comes to mind are favored weapons. Is this a bug or are deities really (mechanically) forbidden in Core Campaign?
