I think that sometime in the past the maximum number of exploration treaties a player could have was reduced to one because of problems they caused. Is the maximum number one or not? I ask because I have a game (Crusade 2.323 Opt-In) with 3 active at the same time.
All of these treaties exist because three different AI initiated a trade and offered an exploration treaty as part of the deal. I accepted in every case.
Am I wrong about exploration treaties being limited to one, or has the number allowed been increased, or is there a bug?
