yes, I had that too and was buying the grade 2s in the GTM. But then once I started seeing the grade 2s on planet, I stopped seeing the grade 1s as well, and now a couple planets later I'm noticing that the 100-something grade 1s I saved up are now gone, and I can't craft things that require those, which seems to be most things. But it could be entirely possible that I'm mistaken. I also did not know that you could redo the early missions, I just show missions for grade 2 metals and compounds, so I've got a decent amount of terenthium which doesn't do much without the desh needed also.

This has probably been mentioned before, and I may be in the wrong section, but it seems mostly appropriate. When I started out scavenging on the early planets I was finding the base metals used in every crafting I have, but now that I've moved further into ch. 1 I am finding that I'm getting the higher grade metals which is great since you need those; but also I'm not getting those lvl.1 metals anymore (i.e., desh, silica) and my reserves are starting to run out. aluminum is particularly an issue as I never seem to have built up stores of it. Am I then relegated to buying base metals from the GTM unless I want to run around my starting planet at way too high a level looking for piles of trash?
