Just make sure you save often! Especially as your scene becomes more complex. When I start geting alot of stuff in a scene, I will save after every other change or so, overwriting the previous (though it doesn't hurt to have duplicates which can be deleted). Speaking of which, in case you don't already know, if you have it selected in File-Options, Vue will make a backup copy of every scene you save, but it gives it a file extension of ".bak". if a .vue scen will ever not open and you have a .bak file in the same directory with the same file name, rename it with a .vue extension, and then you can open it. Glad the spot example helped. :)
