Describe the bug
For two weeks in a row after Flamegor when doing /dkp bid [item] a LUA errors pops up, forcing me to /reload
Also when Awarding an item the LUA errors popped up. Maybe a coincidence but it happened 2 raids in a row after Flamegor, before the Chromaggus packs.

EDIT: I see I only saved 1 lua error (according to the lua it's the 'award' error)
