It's pretty well documented that Litany of Larceny is bugged. Specifically, if you took Left Eye of The Falmer there is a chance that the quest will bug out and moves into stage 200 (completed) instead of 80, which would've allowed you to sell it to Delvin for 1/5 of its value. There is also the problem of not getting them in the correct order and you can't sell them to Delvin anymore (because the quest has already moved to stage 200)

The question is: will this affect the player's ability to become the Guild Master?

I'm curious because while the items have not all been sold, the quest has lready moved to completed state (stage 200). Has the game registered the quest as completed or it's the kind of "noonly looks like completd" complete?

There are lengthy discussions in UES about this, and it seems that Delvin simply won't accept the last item that you take, no matter what the last item is (for folks who do it in order, it's Left Eye of The Falmer, for me it's the East Empire Shipping Map). This implies that the participants CAN progress through the Guild smoothly, with only 500 gold missing. But I want to make sure

I'm thinking of resetting the quest and add the items one by one via console to truly "finish" the quest, but I'd rather not have to do it

Fortunately, the larceny targets have no effect on becoming guildmaster. You should become guildmaster once you've restored influence and completed their questline.

And yes, once you pick up the left eye of the falmer, the quest simply goes to completion, leaving you unable to hand the eye to Delvin. Me, personally, I just sold both of the eyes for a hefty profit after I became guildmaster.

Thanks for the clarification. Now I can sleep easy
