We just unlocked box 5. A red flag was raised because of the new temple building that we unlocked (The 40 cost 'spice' building that gives 3+ explore for each ancient statue). With the rules and milestone surrounding this new building it made it out to be kind of a big deal.
However we already had a temple unlocked in box 2 or 3 I think. Now we have 2 temples. No one had built it yet because of its cost. My question is: was there supposed to be a temple in an earlier box or is this a component error?
