After trying everything to get my talent points back after a DK server transfer, (I only have 20 at level 85 with a raid in 3 hours). I deleted my DK in an attempt to restore it to see if that fixes it, now when I attempt to restore the DK it states "There was a problem restoring your deleted character. Please try again later.
The missing talent and quest issues are known issues that we’re working on, both to resolve the core issue and to restore lost data.
Not being able to restore the impacted character is due to the 1 DK per realm limit. The limit can be bypassed by transfers, but the restore tool respects it. >_< For now, please do not delete any characters impacted by either the talent or quest issue.
