Currently trying to buy items for gems using macros. When using /craftqueue buy 1 and then highlighting the gem, the merchant will sell ingredients for completely different gem. This has happened multiple times while buying ingredients for level 1-100 gems.
Example: Use craftqueue buy 1 macro to buy ingredients for Raw Airy Primal Rune, which should be 1 Lo Gem, 1 ground vendo bone, 1 air elemental essence. The merchant then sells me 1 Lo Gem, 1 bloodied battlefield dirt, 1 heat from unearthly pyre.
