Quest Arcane Reavers is unavailable for undead.

I use questie 7.4.14 in Wrath of the Lich king classic and it marks Arcane Reavers quest as available for mage undead, but this quest is unavailable.

Wowhead classic marks it as available https://www.wowhead.com/tbc/quest=9487/arcane-reavers but it looks like it was changed. Modern wowhead https://www.wowhead.com/quest=9487/arcane-reavers shows this quest as available only for blood elf.

Addon installed in "classic" directory.

Wowhead's TBC database shows the Undead issue, but their Wrath database (just like their Retail database) shows only Blood Elf. This was likely a manual correction on Wowhead's part (versus our shared source database) and we'll make the same correction going back to TBC as it was likely intended.
