*the companions quest spoilers*

I had previously finished the main quest line of the companions but had continued to do some of the side quests. I noticed recently however that Skjor is now back in the companions stronghold and giving quests too, which should be impossible due to completion of the main quest line. Also, Farkas has been refusing to give me the dialogue for side quests from him after the main quest, but I think that's been that way since before the latest patch. However he does give the dialogue option when you accept a quest from another companion, but only to give the response that I'm already doing someon else's quest (like all companions quest givers will say if you have an open quest from one of the others).

*Hircine quest spoilers*

Another NPC inexplicably alive after their quest, but since I have the saviour's hide he should clearly be dead. He doesn't really interact with you, but will kill anything hostile in the main part of the grotto where you find him and will not move out into the two paths joining it.
