Aela the huntress somehow got killed by a dragon after finnishing a quest and i did accept a new one, but now when she is dead, i cannot turn it in, and i try to get a new quest but all keep telling me to finnish the one i got with Aela.

Any ideas?

none besides loading an earlier save file... that svcks, seems companion quest line has tons of issues, I'm stuck on "Rescue Mission" given by Vilkas, where Nazeem disappeared and needs rescuing (apparently numerous NPCs could take his place, but it's always the same mission). The quest marker is in the wrong location first off, but after reading the description I found where he's supposed to be. After killing his captor and unlocking various cages it says "Talk to Nazeem", but he's nowhere to be found. Quest marker remains in the same incorrect location to the East, in between the actual quest area and Whiterun. I had a "genius" idea at one point to use Clairvoyance, which leads me back to Whiterun, but once I'm in Whiterun it says "No direct path could be found." Basically, he was probably supposed to run back there, but somehow didn't make it, and is now lost to the void, preventing me from completing the quest and moving on with the Companions quest line.

Worst part is, I know the whole "load a previous save" trick, but I did a ton of other quests and played for like 5 hours before realizing how badly glitched this was, so assuming there's no real fix I'm just going to plow ahead with the main story. But, a heads up to all of you, save a new file before accepting this mission from Vilkas, which was the first one I did after joining the Companions. What a kick in the nuts.
