[Xaertis]

But I actually do. This has happened a few times, but most recently when going through the process of unlock Rune Magician I was talking to the NPC and he told me to discuss [Rune Basics] with him next. It appeared on the left side of the chat, but it was also highlighted in the chatlog. I clicked the highlighted one in the chatlog and nothing happened except for this message:

System: You tried to discuss a topic you didn't have. How did you do this? Please report it on the bug reports forum.

Clicking the [Rune Basics] button to the left fixed this issue and let me continue the chat.

This issue seems to happen any time the NPC offers a highlighted message in the chat and you click on it instead of the message to the left side.
