What is "Singular"?

[AutomaticCoding]

I did search around the forum, found nothing.

I keep getting the error:

[Singular] Starting Singular v0.0.0.0
[Singular] Determining talent spec.
[Singular] Current spec is  Holy Priest
[Singular] Using CreatePriestCommonCombatSpells for Holy Priest - Combat (Priority: 999)
[Singular] Singular currently does not support Pull for this class/spec combination, in this context! [Priest, HolyPriest, Normal]

It quests fine, but, doesn't attack back. How do I fix it?

Just download an other CC: Priest

Singular is called the default CC pack that comes with Hb

as wownerds said just use a custom CC because your build is not supported by Singular
