I think I mentioned this in the Skype chat, after Lucius had stated that they wouldn't likely be taking part in the missions, but I'll notice if and when a mission is being neglected. And, as a Co-Gm [i](& with the go ahead from Cynder)[/i], I'll make the decision to either have the mission played out as expected, or write up a new mission reacting to the failure of the neglected one.

Simply put, neglecting a mission will likely result in consequences that may take higher priority over other mission lines.

EDIT:

I'm also toying with the idea of not releasing new missions until the current ones are at least started. If a mission loses a member mid-playthrough, causing a serious delay, depending on the actions of the other members in that mission, I could either allow them to complete it or fail the mission.

I'm still ironing out the details though.
