So skjorbis alive somehow after completing the companions questline and I can even get work from him. Anyone else had this happen?

DON'T TAKE WORK FROM THE DEAD SKJOR!!!!

seriously. If he returns in your game after dying. Avoid him. Its a well documented fact that you can seriously damage your save games. Someone has even stated they got stuck in Jorvaskr and couldn't get out after taking a task for him. Others have stated taking a task for him ended up being unfinishable and there for they could not take important ones from Farkas, Vilkas or Aela as "don't you have a task to do still?" simply came up every time.

I had a glitches like that on another save without Skjor but thanks anyway
