I can only imagine re-logging was crucial to gathering guardian artifacts as well.
What are you doing?
Exigious claims his ways are the only correct ways to do things and doesn't say the alternatives in his "tutorials". He's not really a very trustworthy source of info in this regard. For Example: His tutorial on unlocking Palin just tells you to go to a crash site, log in and out, and he says "If you're doing it any other way you're doing it wrong". This is actually a lie:
He doesn't mention you can go to a Thargoid structure and get the sensor fragments through combat with the scavenger drones there, and you can do it fairly quickly. It's a lot of fun in my opinion, and there are amazing assets to see and a puzzle to solve if you haven't already done so. So there are alternatives. But this is not the "wrong way". The same applies to guardian artifacts, find a list of sites to visit from the cannon website, get the ship you want, and go visit them. It helps break up the colleciton gameplay with a bit of space travel (which I think this game excels at).
In would say just don't listen to Exigious if his tutorials make you not want to play the game (that's how I feel about them). He's obsessed with min maxing when it comes to collecting mats because he sees anything other than that as a waste of time, if another method is 10 percent slower or whatever he just won't tell you about it. I prefer getting things like fragments and materials from sites organically through gameplay, and I just visit a few one after the other rather than stay at one.
