First of all, a big thanks @blackrack for the wonderful work. I had a bug report, didn't see it mentioned anywhere. Sorry if it is already known.
On a stock 1.2.2 install, on exiting from the space centre to the main menu, the "Mun or bust" screen appears. But with only scatterer 0.256 added to stock, the main menu is kerbin, not the mun or bust screen. Not much of an issue, but it would be interesting to know why.
