recovery dialogue keeps coming up on reopen of saved project

So I keep getting the new recovery dialogue box coming up when i open my project
BUT i exited fine and saved all - what is it doing ?? Why is it asking me to keep recovering stuff
If I say no am i going to lose stuff ??? This makes no sense

When i say no it doesnt seem to lose anything but its really hard to tell .
I would reallly like to know though if there is a risk of losing stuff .

i exit the project and save all // everything is saved already
thanks
