I have noticed this annoying bug for a while now. I am a level 36 and was doing the Miranda Dungeon quest. 3 times I have experienced this bug. I was doing the quest solo. When battling the battle with Mayor Grimm he seems to have shoot from his feet. I also have experienced my companions losing health after every each battle. You can check out my other forum: Miranda- I am furious in the Cool Ranch section. You will also see another player has experience the same problem as me.
