While using ZCL Alpha 004, (The one packaged with Build 704.) even if the ZQuest-Tab "Load Last Quest" box is checked, ZQuest won't start up that quest on opening.
It seems that even when not using ZCL, this error occurs. It won't automatically load the latest quest you had saved in and exited normally from.
EDIT: Heh, y'know, I thought I felt something funny while posting this. 😛 Thanks yo.
