Current questions and answers regarding the map editor.

A small question regarding the prophet's hut. I created it using the editor and the standard Quest interface. I decided to set the reward type to AWARD_SPELL.
However, regardless of the Spell_id that is set, when playing the game, the reward displayed in the hut's window is "Unknown." (Although the correct spell is awarded upon completing the quest).
Is this a bug in the editor itself? Is there a way to work around this without fully scripting the hut?
