Grand Heists are bugged. Don't bother wasting your time like I did.

Grand Heists seem to be bugged. Ones with obstances that require brute force to open, the npc just stands near the edge of the obstancle and does nothing. I went backwards to reset the npc but he still keeps getting stuck. I've done 3 seperate grand heist I got from levelling and ALL were left uncomplete because of this bug. Very annoying and frustrating because I decided to heist first time in a while.
Please fix :)
