basically i messed up, i went on this quest and got to dustmans wherever, then i had to go, so i think i just walked out, saved and went off instead of saving inside the cave, why i did this i do not know but i almost forgot about the companions and went back to them because i couldnt find the quest in my journal or on my map and all they say is "[that guy] has given you a job to do, so get to it" but hes at whiterun and i have no idea how to do the quest! also i cannot load from a previous save as ive made too much progress since then and deleted all of my old saves, i know im stupid lol
