As I mentioned earlier, I wouldn't worry too much about it just yet. The changes that lead to the Aberrant War are large in number and occur over a long span of time. The penny starts to fall in May, 2015, and finally hits the floor in 2040. Twenty-five years is a long time for something to drop and many changes will occur subtly over that time.
To be honest, the best thing we can do is put in very subtle changes regarding baseline and nova interactions and the degree of a war between separatists and intergrationists (hey, you give me a term aside Monkey-Lover :p ). Again, we're talking twenty-five years... not to be a curmudgen, but how likely even one of us will still be here that long?
