Whenever a storyline NPC contacts V, it drives me insane that the mission automatically swaps to whatever that NPC is calling about; this seems to happen most often when I am traveling to another mission I want to do at the moment. Often, I'm traveling by vehicle so the path on the minimap changes and I end up going out of my way, particularly when the new story mission starts out on the same route as to where I was going in the first place. When I want to get to that storyline mission or any other, I'll find it in the Journal or world map, Thanks!
