If you load a quest and immediately go to graphics>tiles, ZQuest will crash. If you modify the quest in any way and then try it, it will work.
This bug occurs in Windows build 1002.
[1002] ZQuest: Graphics>Tiles crashes if quest is unmodified
Not confirmed. Does this happen to every quest?
Yeah, I can't confirm this one either. It might have to do with something in that specific quest.
Thrice unconfirmed. I don't think this a bug currently.
