Blizzard have shared that the technical issues that were causing players to get the wrong Twitch drop today have been fixed and those affected will get the correct drop and get to keep the mount which arrived ahead of time! You can read more about this month’s Twitch drops here.

Hello. Wires were crossed, and we’ve un-crossed them.
For the rest of this first week of the promotion, players who claim the toy will receive the toy.
Players who previously received the mount will keep the mount, and they’ll also get the toy. This may require logging out and back in.
Players who do not yet have the mount can earn it next week, as expected.
We apologize for the confusion!
