[DOTA2] hero_pool event not working for Single Draft matches

Related Games:
Dota 2

Related app/team name (not a must if you want to keep it private):
DotaPlus

Issue Description:
The event stopped working for Single Draft. It should show an array with the pool of available heroes.

Can you reproduce it (exact steps to reproduce):
Just create a lobby with Single Draft as game mode

Impact for my app: [e.g. x% of the users complained about it, it’s a show-stopper]
This game mode is used for low priority matches, which happen quite a lot for many users

Do you currently have a workaround?
Nope

Hi,

We added the bug to our backlog. Currently, there is no ETA, but I will update you here once the fix is released.

Thanks.
