Dark Dreams of Furiae - a new module for NWN:EE! Buy now
As soon as I loaded up my BG:EE saves in the new SoD engine, Coran suddenly reminds me about killing the wyverns. This happens in my save, quicksave and autosave. Furthermore, I finished that quest more than 30 ingame days ago. I have no mods installed, and don't know if this is a dialogue glitch or if he's going to leave soon.
UPDATE: I spent about ten days sleeping, and right enough, he left to hunt the wyvern
