whenever i’m motivated to do something in UE4, it either takes for ever to boot up or has a big update, and then the auto save feature is constantly blocking my work flow.
sorry, this is more of a rant, than a question.
It boots quickly for me and each update just makes me happy!
You can turn off autosave.
I personally never switch to the latest version instantly after the release -> I always update it when I’m doing something else 
As HavocX mentioned, just disable the autosave -> Edit > Editor Preferences > Loading & Saving > Autosave (but then dont forget to save your progress! 
)
