Whenever i am trying to right click a player and pressing his/her number, nothing is happening. Tradings and looking for character info should appear but it's nowhere to be found. What specific add-on is bugging this feature?

I quit the game and plan to play it "very" casually as i just learned that miko is already released (I have waited for her then quit just to learn that it was released after 1 month). I doubt i will be playing 315 dungeon anytime so i at least want to grasp what have happened to the 315 Fantasy Library as I am very curious what led to Vakarine Capture. You can PM me the story inside as to not become a spoiler for others (i think?). I will appreciate anyone who will provide the context of that dungeon. Thanks!
