Hey folks just played a game as Dynamo, matchID 20475540. Around 27 minutes into the game I pulled the Seven with me when using quantum entanglement but I did not hit the middle mouse button prior to casting it.
I think what might be happening is that I set self-cast to press and hold, and it's doing that for the ability and calling it alternate cast? If so, it's a bug as it says mouse 3 in the tooltip.
