I got teleported to the radiation area and died when loading the game.

I play the single mode.

Today I open the game, suddenly I got two achievements, 'On top of the world' and 'Neil Armstrong', then I died and the game crashed. Then I restart the game, I got another achievement 'Dig deep', then died. When I was reborn I found my bag was in a place I have never been and it is even not shown on the map, I tried to find it but it was in the radiation area.
