One thing i do in case of situations like this where you don't want to lose work if you lose all settings is, prior to starting work i do a C3 to find table Zero.
Then i manually jog over to my material X,Y zero (I usually set mine in the center of material). I then write down those X,Y coordinates. Then I Zero X,Y.
So now if the gremlins sneak in on me during or between cuts all i have to do is go back do a C3, MX24, MY24 (or whatever the written down coordinates numbers are) and i'm back to manual center of the material even though all settings were lost like in your situation.
