is that we can't trade during trader upgrades. i know that we can use instants. but those have become a lot more valuable now w/ crafting and trader upgrades can take 40 hours. our wonders still work while they're being upgraded. our homes still hold people while they're being upgraded. we can leave trades on the trading block, we can harness the magic of powerful wizards, dragons, woodelves, and elemenntals but we can't have traders from other cities come to our city because 1 building is under construction? i think that someone didn't think this through very well when they thought of it. this rule is a major inconvenience for team players and punishes younger cities that depend on larger fellows more than the city that actually does the upgrade. now this dumb rule is starting to reoccur every single chapter. just think of the new players that are just starting the game, need trades, and were left all alone in timbuktu because someone only moves cities once per year. do we want to find more ways to frustrate new players?
