Guild Wars 2

After finishing the other tasks to assist the bandits in the camp, I spoke with Karl Codecracker (the last NPC activity I had left to do at that point).
After accidentally clicking the “x” (I’ll do it later) option, which closed the conversation box, I could no longer get the dialogue box to pop up when speaking with him, so that I could choose the “checkmark” (to assist him in cracking the code) and continue with the mission.
I spoke to other NPCs in the camp with the hopes of resetting him, and then waited for 5min, but I was unable to get the dialogue options box to pop up again, and had to quit the mission.

I don’t know if the same thing would happen with the other mission-activity NPCs, since I didn’t click the negative option in their dialogue boxes.

This bug still exists.
