Grabbed DSO for $5 through Steam over the holidays. One hiccup I found was that the rest of the Stromok system was discovered, but I couldn’t get to Odia, which is pirate infested, and hence, grants an artifact when you clear it.
As it turns out, you have to
head to Cabracoy first and complete the sidequest there.
Took a bit of searching to find, but hopefully this helps you.
