I've been playing through No Man's Sky, and have upgraded almost everything as much as possible, but I'm having trouble gaining the "Salvaged Frigate Modules" (SFM) required to upgrade my freighter. I'm picking that in the 115+ hrs on this save I may have received maybe 15 total? And I haven't received any in the past couple weeks.
I've read that you can get them through Frigate expeditions, so I'm sending my frigates out on all 5 available expeditions every day, usually 4- or 5- star fleets going out on every expedition (even on the 1-star quick ones), but I rarely get any SFMs in the rewards. (as an aside, I also never see expeditions higher than 3-star, so maybe if I was seeing 4- or 5-star expeditions there might be more in the rewards, but I don't know)
I have also never found any at Crashed Freighter sites, nor from attacking fleets, and I think I may have received 1 or 2 on a Nexus mission.
Is there a quicker, better, way of getting these? I only need a handful more to finish upgrading my freighter, but this is getting frustrating!
