I agree with your comments on vue regular saves are the way to go ,I have a system by which first save is scene name 1 then small changes will be scene 1a 1b 1c etcthen big changes become scene 2 then 2a 2b 2c etc that way I can always go back only a small step rather than having to redo loads . since having the new system vue has not crashed on me yet (touch wood). one thing I have discovered which I was un aware of , i have a gamers keyboard with a small display that amongs other things show cpu usage and RAM usage it would appear vue holds on to the ram more and more as time goes by , the picture Im about to put in the gallery used 17% of my 32GB of RAM when everything was in the scene , eventually after multiple test renders but only changing atmosphere and moving the dinos RAM usage went up to 71% Exiting VUE before the final render put the used RAM back to 17%
