I finally found a working raw mats trader after an hour or two of messing around and it looks like some materials are incorrectly graded.
Even so, the crashed conda at Orrere lets you fill your boots with G4/5 raw materials which you can trade around, so I'm not sure what's gonna happen there. I checked it out on the beta server and it's still there (for now). (Antimony, Ruthenium, Tellurium, Tungsten and Zirconium if memory serves).
Orrere 2B 43.8 -173.9
I'm not sure if they are buffing returns from prospecting/mining, but I don't really have a baseline for comparison so I've not checked that.
If they do, then the crashed conda (and others like it?) will be less relevant.
Parking guidelines:
It's basically pitch black down there (I enhanced the image) and not very flat, even though it looks it.
I'm going to park CMDR Likewise down there for a bit so if anyone wants a wing beacon to fly to, let me know.
Scan the datacore dooflipper in your SRV before you leave too so you get a beacon for next time. (I mention this because, y'know, I forgot /flex).
