Yes i am finding that as well. That particular mission i ended up trying to shoot my way out and ended up with a $190 bounty. There was no other way out i could see as they were all just trying to kill me and the only way out was through the front door. The amount of times ive shot someone accidentlly as well is very frustrating. Then the witness runs off to grass and i either have to run or follow and kill the witness which normally just escalates the problem.Same here got inside and clocked the safe on the wall before realising I didnt have any dynamite to blow it. The only way im making money at the minute is flogging stuff to the fence, all keeps going on the bounties im accidentally racking up.
Lesson learnt for me is violence is to be avoided where possible otherwise all my money goes on bounties.
