Numerous spells are using an incorrect spell visual in Classic Era and Hardcore.

• Developer’s Note: As part of the process to import spell visual assets for Season of Discovery some spells incorrectly had their animations overwritten with the Wrath of the Lich King version of the spell visual. We hope to put out a fix to correct this within the next several weeks.

They know.
They’re working on it.
