The quest Your Fortune Awaits You..., from Sayge's fortunes in the Darkmoon Faire, actually has 4 versions leading to different objectives; only one is correctly marked as repeatable in the Questie database.

Version 6.1.0

Are you sure these are repeatable?

I completed one (the one that leads to the logging camp in Elwynn), and using the IsQuestFlaggedCompleted script still returns a "false".

Also, an old DMF rep guide notes that these quests are a cheap, if very slow and random, way to grind to exalted.

Thanks for the report. Will be fixed for next release.
