My new city is in Carthage and still in IA. Three of my last five Daily Challenges have included a "complex negotiation" and today's included a "very complex negotiation". The goods required to complete any of these negotiations significantly exceed my daily goods production. I've no event buildings yet, no GBs that produce goods, and these negotiations would be impossible to complete without spending a lot of diamonds. I've chosen not to do them. In my LMA city I've never seen a "very complex negotiation" and "complex negotiations" appear in Daily Challenges approx. twice monthly. So I am wondering why my Daily Challenge difficulty is higher in my IA city than in my LMA city and to the point that it would require many diamonds. Did I do something there that triggered this??
