At the end of the widowmaker mission, Mary said if you ever need to use the widowmaker, you don't even have to ask. Where is it? How to use it? Can it be used after the mission?
I just checked and the widomaker is not in my garage menu, checked every category even the locked ones. I did finish the widowmaker mission, brought the truck back and parked and talked to Mary. I think it may be another bug.
