Map Editor: Exporting while the magic finder is open causes a black screen
Map: Custom
I've repeated this. What I do is create an action (ie. cast spell), then for the target I click "World", then while the magic finder is open in world view, hit escape and "export/test". You'll get a message like "export successful" but the map won't load and you'll have a black screen. You'll need to alt+f4 to get out of this bug.
