I've taken my miner out a few times since the last publish and have noticed a decrease in the amount of colored ore and gems he finds. Pre-patch, I would do a quick circuit in Ter Mur and come back with a healthy amount of colored ore and usually 5-6 gems/crystalline blackrock. Doing the same circuit post-patch, I'd say there's a 50-75% decrease in colored ore and only 1-2 gems or crystalline blackrock.
Maybe I've just hit a rough RNG patch?
