Quote - since when have they fixed the interface bug that overloads it's memory and crashes the application + bonus* chance on killing the saved file aswell? 

I'm having atleast 9 incrementals per 4 hour project..

I imagine you're pushing it too hard in some way or another. Check the size of your texture maps, then the number of instances of eco-systems. Or parametric terrains? There are plenty of shortcuts for all of these problems-- if you need any help with them just ask.
