I have completed the Companions questline, cured Farkas and Vilkas and myself. Killed all 3 wolf spirits, and I no longer have Beast Form and can gain restful sleep.

However, it is still tallying up days as a werewolf under General Stats, and idiot guards still occasionally make werewolf comments to me (fur growing in ears, etc). I need this to stop. Please tell me how.

It's a bug. Hasn't been fixed in any patches yet.

There's no console command or anything? It is so annoying! Surely I won't have to download a mod that prevents NPCs from greeting me...

I don't play on PC. But there are no console commands to fix this that i know of. Try searching for it on the UESP

I don't play on PC either, but do players belong to "factions"? If so, maybe you can take yourself out of the werewolf faction.

Just pretend it says "days sense becoming a werewolf" As really I'd put that bug on the stasitic page as absolutely last on the list of things to fix.

I'll simply download the no NPC greeting mod so I don't have to hear the idiot guards mention fur in my ears every 5 seconds.

The player gets put into factions thru-out the game. There is a Werewolf Faction you get put into and as long you are in this faction, the guards will make those comments.

There is a main faction the player is in to make sure NPCs/creatures are hostile/friendly to the player.

Well, there you go.
