I'm having several issues with Carbonite and with all these issues I thought I'd put them all in one post.
1) The objective is not listed in the database. This happens in all areas regardless of expansion level. For instance, today I got this questing in The Badlands doing "All's Fair in Love, War, and Archaeology".
2) Incorrect quest destinations. Example: "Into the Dragon's Mouth" sends me to where Rhea used to be in Lethlor Ravine when she is, in fact, in Dragon's Mouth (note that this is an Alliance quest.) The quest itself says that she's no longer in Lethlor Ravine.
3) Incorrect quest destinations two: I find that Carbonite sometimes ponts to quest destinations for Horde rather than Alliance locations. For example, with the quest "The Venerable Doctor Blam" Carbonite wants to send me to New Kargath.
4) I often have to reload the interface in order for the Carbonite quest list to update properly, often when problem 1 occurs, but not always.
