So i had a few different bugs happen in a row very quickly.
First - The dig location i found a grave, the dig location popped up on the map couldn't dig anywhere i know this is a common bug atm.
Second - Teleportation bug - I left the grave turned around and started to head towards a mail box to open it. While going towards the mail box i went to jump over a bench i ended up falling out of the air about a good 100ft right of the location i was at.
Third - After those two bugs i went to the walk about quest location, popped my lovely joy pill the quest started but nothing really happend. the ghost spawned then just stood there. if i moved around after a few seconds the ghost would turn and look at me and that was about it until the joy wore off and i started to withdrawal.
