That is, does the program 1) complete the expedition, and then 2) do a RNG die roll then? Or are Artifacts kind of scripted? As in, "This one appears after the fifth expedition. This one after the ninth." Etc. If a RNG result, would it be possible to Save just before expedition, then expedition finishes with no Artifact, then Load the Save and keep doing that until an Artifact appears? Is there a definitive list of available Artifacts anywhere? Any mix formulas to tell what any three given Artifacts will yield?
