Skyrim no Markarth job for under new management special quests

This is for the "One With the Shadows" achievement right? The jobs are chosen at random, so just quick save before you talk to them, if it's not Markath quickload and try again, that's what I did.

Here are your odds of getting a Markarth job:

• Bedlam (Delvin, Dragonborn not installed): 20%
• Bedlam (Delvin, Dragonborn installed): 17%
• Numbers (Delvin): 15%
• Heist (Vex): 14.3%
• Burglary, Shill or Sweep (Vex): 13.8%

The odds for Fishing jobs are a little tougher to figure out, and are highly dependent on how many citizens of each major city have fallen to Vampires, newly minted Werewolves, Dark Brotherhood members/wannabes, or Forsworn mass jailbreaks. Also be aware that the Dragonborn DLC dilutes the target pool for Fishing too. YMMV
