In the bad old days there were the dreaded Arsenic, found only by driving around aimlessly on a planet, and Chemical Manipulators only at Dav's Hope for lawful pilots. Cracked Industrial Firmware was also scarce before traders. I really think FD have fixed all the problems these days though.
I indeed struggled to find arsenic for a particular engineer, indeed only finding it on certain planets - it wasn't that hard to find once I did a web search or three, but I basically didn't have any until I went looking for it and didn't know I'd need it until I did!
Something that has become worse now in "legacy" mode as most of the websites dedicated to helping you find things in game are only tracking "live" mode now, so you mostly have to rely on out of date sources!
Indeed it's something I didn't think would become a problem so quickly, but it's already a lot harder to play "legacy" mode now, than it used to be - for example, I just funded unlocking Selene Jean and I was trying to use Eddb.io to sell my extra wares at a decent price and none of the good prices listed there were anywhere to be found in "legacy" anymore!!
Sure during busy CGs it wasn't particularly accurate, however after going two or three places, you'd find high prices matching their list, I went to about six stations finding terrible prices, so I guess I'm better off "throwing darts at the sky" again, to find good prices (and many other things in game now)!!
