zLegendary items from UD and TMQ are bugged and are untradeable through trade screen and auction house even if you don't wear it. The only way to trade it is by player own shops.
Picture for auction house
Also the legendary drop rate from mobs are still broken, Regular mobs are suppose to drop legendary rate items, but right now not one single mob drops a legendary item outside of UD and TMQ which @Daneos said he fixed a long time ago but actually he didn't. He fix the drop rate % for it but didn't add the drops to all the mobs.
Another bug about Legendary items out doing 100 TMQ1 Hard I RECEIVE ONLY 2 LEGENDARY ITEMS ON MY 77TH ATTEMPT I got my first legendary drop(picture in spoiler below).
This type of drop rate for Regular Mob is acceptable, but for TMQ and UDs from Heroic and BOSS mobs this drop rate is just disgusting and terrible gameplay mechanic which will make people in the future not even bother to spam it, which will turn into dead content. My suggestion to make it better overall is to give it the same drop rate chance as the sliver coin you get from killing the Majins for the BOSS Event.
