The rebuild is designed to take time, as such ideally the player (you!) would be doing other quests and adventuring between the stages, however we recognise that some people will have run out of things to do and may wish to speed up the time between the stages a bit.
Having said that, here are a couple of things to bear in mind when waiting:
With all this in mind, Weye is an example of a good location to wait
You can use GameDaysPassed in the console to speed up waiting. However please note that if you are a bit over eager then you risk some scripts not updating properly. The following times should be used as a guide only between stages. They should be safe if used propely, but no guarantees. The command you need is:
Set GameDaysPassed to GameDaysPassed + X
(where x is number of days to skip)
The waiting periods are as follows (pay particular attention to between 'Blood on the Road' and 'Falling Flowers').
