Yea, he ditched me...
Just as a note : Before i joined the thieves guild i completed all of the fighters guild quests
I was completing some quests of his and there was no way to complete the bitter cup quest because Eydis fire-eye was already dead, so then i finished the quest with Hyrundi and Stacey said "no more jobs untill you become a mastermind"
I didnt have a thieving skill quite so high at the time so i decided to do a few bal molgamar quests...
I finished the Hlervu locket quest so i recalled back to Stacey's hideout... and after reporting to him that i completed the locket quest, i saw Sjoring Hard-Heart's name on my list...
I asked him about him and since i already killed him, he congradulated me and gave the skeleton key to me.
Then i got another bal molgamar quest with the land deed, so when i came back to his hideout after finishing it, he is gone...
I trained up my skills and talked to Sugar-lips in balmora and advanced to Mastermind but still, stacey is gone... whered he go?
