None of my global items were equippable, except for music and loading screens. I tried to equip them using the armory, heroes tab, right before a match after I selected a hero. One of my announcer packs showed to be equipped, but it was unchangeable and the default announcer was used anyway. My Nature's Prophet and Death Prophet Mega Kill announcers were somehow deleted when I tried to equip them, but not their Announcer Pack counterparts or any other Mega Kill announcers that I tried to equip. I unbundled a Kunkka and Tidehunter announcer bundle, which immediately caused my Dota 2 to crash. I reopened it, and it showed the bundle items to me without me doing anything. My global items are working again, although my NP and DP Mega Kill announcers are still deleted.
