After snapshot 15w38a, slime blocks were acting weird with the player, sometimes do not push you away, acting as a normal block

I couldn't see problem. Seems to me it works fine.

I'm experiencing exactly the same problem. The slime block sometimes does launch the player into the air, sometimes it doesn't.
