Jarl Korir won't give me the said quest, I must have been rejected(i.e. pressed ESC during the quest dialogue) way back and now I've been trying to make him so that I can become a Thane of his hold. I've tried some console commands(i.e. recycleactor, resetai, disable/enable) and I've been scouring the internet trying to find a fix for it.

I have the "Unofficial Skyrim Legendary Edition Patch" installed using M.O.(Mod Organizer) and have not yet progressed through the Companions' Questline... Although loading a REALLY OLD SAVE fixes the issue because I've never been to Winterhold that time, but the problem on that save is I'm WAY BACK to the current progress I have and I don't want to restart my gameplay because of it.

Side-note: I DON'T HAVE any "Dungeon Delving Quest" ACTIVE.






And yes, my copy is legit. I've bought it on Steam. <- (Comic Sans MS)
