I died whilst trying to 'return to the safe house' on the arena mission. I re-spawned in the safe house but no matter what I did it would not complete the mission. I did some research and quite a few people have encountered this bug. I contacted the dev. team and they said the would "look into it". Three months later and still nothing...I haven't played it since and wont until it is fixed. Very disappointed, it has ruined my experience of a game I was really enjoying.
