I mean Lorenzo the loan shark from The Hub, in F1. Tried to kill him as chirurgically as possible. You know, like erase him (couldn't stand this guy's philosophy ). So I planted 2 dynamites in his pocket (now that I think about it there' might have been better ways to clinically remove this guy) and ran to the Heights so that his guards would not attack me.

Problem is, no matter what I do after the explosion, when I come back to downtown in order to loot his body, the game bugs.
To be more precise, as long as I stay in Downtown and do my stuff everything is fine. But as soon as I try to save the game or leave downtown for another screen it freeze with the window "Fallout stopped to work properly, etc...". I even waited for a caravan depart day and went directly to the caravan driver to automatically leave the town and it freezes all the same.

Is it because I leave the screen after I planted the bomb ? I checked and found nothing on google.

PS : Found a solution. Had to stay in the same area until the bomb explode. If far enogh, the guards wouldn't attack anyway.
