Hi,

Been playing with a new character and after the "Loud and Clear" quest in the Thieves Guild. I can`t talk to either Vex, Delvin or get the Armor from Tonilia. This happens after Brynjolf tells me to talk to them before heading out too the Golden Glow estate. I assume this has happened after installing a patch because I have done all the quests before from the vanilla install. Does anyone have any idea if you can fix this from the console. Cheers

May have found the solution myself. I had the "give Vendors more money" mod installed. Disable this mod then do the Thieves Guild questline and it seems to work.
