For me it's a busy time, and it sounds like it's the same for others as well.
Having said that I'm not a fan of these sort of games having rules surprises, the interest for me is attempting to solve the problems presented within the given framework. Not having the rules clearly defined is affecting my interest.
Edit to add: It hasn't helped you've been slow to answer questions and make corrections, if you're going to set a deadline make sure it includes enough time for you to come along and respond as required.
Also the more I think about it presenting a seemingly complete scenario and a rule system for that scenario, only to later turn around and say actually the rules presented are incomplete but I was only going to tell you if you asked, is I must say rather poor GMing. Have a game with twists is fine, just don't do so if you're only means to achieve it is to misinform your players.
