I didn't see this covered so apologize if I missed, but how do the completion criteria/prerequisites work within the context of commons updates? For instance, let's say I have a module in commons that I update by adding one additional page and that module update is pushed to another course as well. If a student is in the other course, but has already completed that particular module, what do they see? A formerly completed module that's changed to incomplete with one activity page not checked off? What appears to be no activity in that module as everything (including completion) is completely reset?
