That sounds like a problem on Valves end (since they did a fairly big update at roughly the same time). We dont have anything to do with the lobbies,hosting etc. We can only affect the game it self.

I suggest you report it to the dota 2 forums

Before the update i had no problems with hosting games. When someone didnt load i was returend to the looby. But now im getting kicked out of the lobby and it says somwthing about not ahving the game and alot of numbers after it.

Today we released a small update that make the hook-cooldown be 3 seconds (from 8).
We also removed some old text about the previous platform.

Let us know if something broke because of the update.

Thanks for all the support! &lt;3
