Bumping this again. I’ve resorted to submitting daily bug reports for the time being until this gets fixed/responded to:
Molten Lava Pack is a toy that’s supposed to drop from Invoq in ZC and does not appear to drop after you get the dragonriding glyph from the rare. NO ONE has reported getting this toy after learning the glyph. People have had to resort to making second accounts and not learning the glyph so they can get the toy. The playerbase has submitted hundreds of bug reports over the past few months with no response.
