So I just bought XCOM: Enemy Unknown and all the DLC as it was on sale on Steam. I made it all the way to the last mission and I encountered a bug that I can't find anywhere here or on the wiki. In the final area with the Uber Ethereal the muton bodyguards were invisible but I could see their health and shoot them. I killed one but not the other and then on the alien's turn it won't move or do anything so I'm stuck on their turn. This is quite possibly the worst bug I've ever experienced in a game because now I have to restart the final mission and fight my way back to the Uber Ethereal. If it happens again I'm going to make sure I focus fire on those bastards. I don't know who'll see this since this thread is almost 2 years old but I had to vent my frustration.
