I've got the ToB Official Patch and the ToB Fixpack installed. This fixes the 'character x appears busy' bug. However, I still got that message. So I figured that it wasn't installed atm. So I checked SK to see if the 2 new items that it added (gold and silver ioun stones) were still there. Well, they are still there, so it means that the patch is installed. But if it's installed, why am I getting the character x appears busy bug? I've literally re-installed all my mods double digit times in the last 2 days, and I'm just getting sick of it.
I also seem to have overwritten the dialogue.tlk file with the Sola mod. How can I fix this? Any help is appreciated.

Just to clarify a thing. The fact that you get "x appears busy" message does not mean it's a bug. The message is supposed to be there and appears for many characters who are done talking with you and who are going away.
The bug was that it used to appear for characters for whom it was not supposed to appear. Or it used to appear before they talked to you. That was a bug and it got fixed by the patch/fixpack.

Thanks for clarifying that. I thougt the message itself was the bug.
