Okey it is like this...
Yesterday i played a game, the teams had the following heroes:
Sentinel: Leoric, Nevermore, Sand king, Ursa and Leshrac ( me )
Scourge: Sven, Treant, Slardar, Chen and Warlock..
As we were playing we were often battling mid. I cast Diabloic Edicts ( which hits random targets ) then Treant activates ulti and 4 of them die only slardar is left alive but he is so close to me so my spell must have hit him at least 1 time but he does not take any damage and just runs of with 5-10 hitpoints. This same thing happend twice in the same game. While i am entangled in Treants ulti i can`t attack ordinary nor cast spells and my previous casted spell did not make damage to that guy. Now i ask if any one knows is it possible this to be a bug or it is just improvement in the version ?
