Don't know if this is the correct forum for this, as it's my first post, but I have come across something that may be a bug, but also may be extremely poor luck.
I have run about 20 "Rich" yield investigations for Class 4 compounds and have yet to get a single one of the artifact level item (forget the name, I just know it's aggravating when I need 8 of them to run 2 barrels). This is with a companion with +2 crit to investigation.
I feel I'm just dumping my cash into a bottomless pit of Phriking Phrik here and just wanted to know if it's a known issue or I'm just the worst person at Investigation ever.
