Inside the Chest, there is always White weapons.
1. In the Glitch I kill myself, but don't load last checkpoint, allowing for me to reappear just outside the Deadzone building.
2. I have learned if you do it that way, and you did it while in the water, it should remove the Boat Fast Travel. This is what I assume is what you are on about.
I then enter the glitch way, go to the chest and open it, and it's white again.
3. After then going to the chest as said above, I kill myself again but this time load last checkpoint. Now from what I can tell, out of the 10 times I've tried it's a 50/50 chance of it not taking me back to the Boat.
4. Also from even more testing, I was unable to get any Legendary weapons at all.
Now I am gonna try this 5 hour Glitch.
