[BUG] Quest "Ledger From Tanaris"

[turbofresh]

Although i've collected all the needed items, i can't turn in the quest. Krinkle Goodsteel, the turn-in NPC, has a grey ? despite my quest log showing the quest as complete.

The only way I have found to fix this bug is by dropping the quest and getting it again. Works well for quests where you hand in dropped items. Only problem is with quests where the item disappears once you drop the quest and kill quests. I have failed to complete a few quests due to this.

Unsure if the problem is server resets or something else.

BEWARE: I don't know if you would have to farm the items again for this particular quest.

drop the items to your bank, delete WDB file, accept quest, and take your items from bank

Will have to try this next time it happens then. Any reason for putting it in the bank first? Also by accept quest do you mean complete or did you have to drop it still?
