Hello guys,
i've been using tsm for a week or two, i just started learning Enchanting profession and i decided to use the disenchant tooltip from my tsm addon, but most of the time the tooltip doesn't show disenchant informations at all (sometimes even on the same item). I already googled it, searched on the forum, on the tsm option but everything seems to be setupd as it should. Any suggestion?
