The event card, "you may immediately use the production chain of one of your buildings(any number of times). Can somebody please explain. Does this mean i can use the chain even without the required resources? What does."any number of times" mean? Thank you!
First off - make sure you're using version 2 rules from the base game! On the back they say "v1.4" ... they are available in the files section on this site ...
Production Chains: during the game, if you've successfully activated a building and produced at least 1 resource (with your main worker or an asst) then you may also activate that building's production chain by discarding the required resource resources from you hand or from other buildings (production chain requirements are on the right, bottom, of each card). At the end of the game you may run as many production chains as possible even if you didn't activate the building.
So even with that event - you'd need the resource to activate the chain in your hand and/or on other previously built buildings
