I'm having trouble with the quest "Ulathek the traitor", part of the warlock epic mount quest chain. The dialogue option from the relevant npc called Ulathek does not appear. He says greetings and all I can say is goodbye. The quest does not mention any special items or a step by step procedure. I have watched walkthroughs on youtube which shows the correct dialogue the first time they interact with the npc. Is this bugged or am I missing some piece of information? Thanks in advance.

As a level 19 Troll Rogue I have tried to complete the rogue quest "Tools of the trade" in Undercity. Online it says the quest requires lvl 16 and it's green in my quest log. I have all the requirements for the quest. I'm supposed to talk to a woman there for the "Thieves tools". When I click the dialogue option regarding the tools, the dialogue window closes instantly with a "Goodbye". I have asked players for help and searched online, but found nothing. Might be bug, might be unclear instructions. I hope that someone can clarify if something else has to be done first or fix any bug involved. Thanks in advance.
