Hi. I receive this error when I try to use the Tier 5 Option for some classes, Order Hall Advancements that "Allows to place a work order for an item which will instantly complete a World Quest once every 18 hours."
Disabling this addon resolves the issue, here is the error message it creates:
Error occured in: AddOn: LegionTreasures
Message: Error: AddOn LegionTreasures attempted to call a forbidden function (UseWorldMapActionButtonSpellOnQuest()) from a tainted execution path.
Here is the full taintLog 2
