So, I got Cayo for my server and would like to add activities there. After that I got Kuzkay_Coke and would now like to move the coke collecting to the island. And I would like to disable the blip now. How to do? I dunno. Thats why I ask.
EY! I helped out myself with this one and found a solution for anyone that is facing a problem like I did.
This dudes reply in the comments was godlike and helped me out a lot.
