Update:
Here's an explanation of what changed:

I've read through it, and from what I comprehend about it, I am not in favor of making this change the default behavior for games. Overall, while this system appears to make sense for smaller maps, I am VERY concerned about what it means for the large maps that make vDip such a unique experience.
My biggest concern is that we don't appear to have an option to use the old NMR system, and there's no option for a 0-excuse game. Huge games would become impossible to play given the NMR excuses. Given a game such as Divided States, you NEED the old NMR system to play the map. Games already take a year to complete on that map. Imagine that each time somebody NMRs, there is a 2-day extension. Each time a player goes into Civil Disorder, there's a 2-day extension. Judging by the CD logs for the finished Divided States games, I'd assume an average of 50 missed turns per game, for 3 OVER THREE MONTHS of extra delay just because some players missed their turns. There's a reason why NMR protection is only enabled by default during the first year. My other concern is that in these long games, it's very likely that a player will miss more than one phase. The previous system only booted players if they missed two phases in a row, which meant that it was incredibly unlikely to get a CD just because you overslept or your orders didn't save. I know that I missed several phases in my Kansas Divided States games, and under these new rules, I would have been kicked out of the game long before it reached its conclusion just for missing a short phase here or there, and given how strong the position was, I know someone would have snapped it up quickly. I know that I will be irrationally kicked out of a game at some point due to this system. Unless there's something I'm missing, this new NMR system seems to pose a major threat to the experience of a large map by causing extreme delays and/or unjustly kicking players out of the game.
