some times when i get onto my quests and finish it i am going back to get my reward for the quest from somebody then it wouldnt let me talk any ideas to stop this from happening
It is probably just a glitch or something (similar things have happened to me, too). Just exit to Character Selection, then click on that same character. Or simply log out and log back in.
I get this all the time - where it won't give you the option of interacting with the environment when you should be able to.
Especially in the Pet Pavilion! Sometimes in the Pet Pavilion you just click X and it detects it even if you're not being given the option on the screen to do it.
Most of the time I have to log out and back in. Frustrating.
