My save at the time I was crotch in sneak hidden mode no weapon drawn while at Viki & Vance s place

So I wen on killing spree for (giggles) with the SMG that I just found and it did not end well they slaughtered me

Well when the game auto loaded my last save "while I was hidden" my guy pulls out the rifle and shoots it even though I'm not pressing RT the fire button
I then pull out a stick of dynamite and my guy just holds the lighter over the wick not lighting it

I remember this bug on FO3

I had to dashboard to fix the problem
