btw OP, if you are going to do the relog loop (I'm not advocating doing it or not doing it, just saying) you should only have to quit to the menu. relogging from desktop takes f o r e v e r
If you have to go all the way to the desktop there's something else going on.. And relogging works for mission sites, so you have to take the right mission, the big round satellite not the one with wings (discussed in the link above if I remember the thread properly). The big round ones also occasionally spawn working power regulators, which is why you always check your contacts menu.
Relogging often brings scavs, just GTA their backsides. I can bowling pin 6 at a time when they drop from the dropship. Takes seconds. They fly far sometimes. Fun times.
If there's 2 or 3 of the same mission types I'll take them all, not so much to be "greedy" but crash sites can be on very rough terrain and that just makes relogging not worth it. I'd finish the mission on the rough site and go to the next hoping it's more GTA friendly (smoother terrain).
When you start the instance, wait a couple seconds for scavs to spawn, if they do, run them down (or kill them on foot for if you'd rather but it takes time). When the drop ship comes in, time it so you hit the drop point the same time the dropping scavs do, take them out, look at your contacts to see if the power reg is any good, exit the SRV, check the datapoint, get back in the SRV, back up a ways and relog to menu. In and out of there as fast as possible. I've collected 40+ MIs in less than 2 hours on rather generous datapoint spawns. If you aren't seeing very many MI spawns, head off to the next crash site.. Maybe the RNG God is kinder there.
Would suggest taking missions along the way that have rewards for difficult things like MIs whether you feel like you currently need them or not to delay having to do these types of relog loops. I don't think anyone enjoys this but until FD figures out a way around this, we are stuck. Doing missions is best and trying to avoid running out of things in the first place. Personally not so patient myself, but I DO regularly and often collect mats/data from missions and settlements even if I'm not doing any upgrades currently. Just sell off the surplus if you feel like you have too many..
Things aren't perfect, but the nice thing is there's numerous different ways of getting what you want for what you feel you need and how you get there is totally up to you..
Good luck...
