Meaning you don't have to do a Shill Job from Vex. No matter what, you should have the choice to choose which type of job you want from Vex and Delvin. It will be half as slow, but you can just do jobs from Delvin and still get the guild restored.

If anything, you don't need to do the Shill jobs from Vex to restore the guild. Restart the system, and load the new save and try again. Tell them to cancel their job, save their game in a new save. Hitting her book doesn't check off as complete forcing you to cancel the job to get by, other then that nothing much. There is one bugged job that I know of in Riften at that Diabella lady's place where you are tasked to a Numbers job and the marker is glitched outside the room. What got me the most was that a large part of his motivation for this mod was to get a job at Bethesda. Once you have a special job you must complete it before you can do any future jobs, current ones that are not finished before can still be done. Scrolls V: Skyrim impressed us back in July. The radiant quest system can give you jobs in places that don't restore the guild at all, Riften and other places you already got your special job. Then a special job should unlock, once you finish that in each hold you will completely restore the guild assuming you already did the main quest.

I don't know if radiant quests add to the count, but what matters is getting 4 or 5? jobs done in each major hold.
