When do I select a market when playing expeditions?

Name
When do I select a market when playing expeditions?
Details
There is an inconsistency between the New Age rulebook for scripted expeditions and the End of Expedition rulebook. During the scripted expeditions, players select which market cards to use after revealing the next nemesis. In the End of Expedition rulebook, market cards are selected before drawing a nemesis randomizer. Either method will work for randomized expeditions (selecting market cards after revealing the nemesis will make the game slightly easier).
