Automation is missing

Hi, I set up the automation for group or for audio track and after a while it comes out that it’s gone. I dont know what cause it, but this happends to me twice already. Maybe there is some hotkey to deleate all automation in project or this is a bug? It just removes all automation tracks for example i have some eq movements on and they are gone now. I did have filter cut for some FX automated and its gone now. Im making an album and redo all automation for the project is so annoing.

Also offtop, do you know why cubase continue to ask me to save the project before closing even if i saved it 1 second ago ? It started to happend relatively recently.
