During the passage of Drugged Outta His Mind quest, you may find yourself in a situation where the game will not allow you to continue the task. This is not the result of a mistake or bug. You just need to fulfill some specific requirements, which we explain below.
For the record, Drugged Outta His Mind consists in tracking a stoned biker (Drifter) who is responsible for the deaths of several people from the Copeland camp. As part of this task, Deacon must conduct a mini-investigation that will lead him to the corpses lying next to a small tank.
The game will not allow you to continue this mission until two requirements are met:
1) You need to drive a motorcycle towards the corpses.
2) Deacon's motorcycle must have enough fuel in the tank, as the next part of the mission involves the pursuit of the motorcycle. It is better to leave the bike in this place and travel by foot in search of gasoline cans.
We recommend a visit to NERO Checkpoint west of the bodies that you have found. This place is shown in the image and you can get there by staying all the time on the asphalt road.
Find a can of gasoline at NERO Checkpoint. Take it on the way back and after you find yourself on a motorcycle fill the tank.
Only after both requirements have been completed you can search the corpse washed up on the shore - press and hold the interaction button.
After searching the corpse in this area the wanted Drifter will appear. You can get on Deacon's bike and start the chase.
