I've been fighting Miasmas quite a lot during the past weeks. Since a few days, I notice a significant change in loot: Miasmas used to yield minor artifacts. They don't seem to do that anymore. Sometimes a Miasma used to carry a level 5 treasure chest (containing an "indigenuously drawn" treasure map). Now all you get is a level 4 chest. Did somebody else notice this change? Did the loot on other monsters change as well? Was there a patch I don't know about? Please share your experiences!
