I dont know if I can make it to the event in time, but I just added SaveLevel, entwatch and BossHP for Skyrim and entWatch and BossHP for Predator. Havent really tested them, but I think they will work.
I assume that the broken pushes (boss attacks, etc) are fixed now.
After spending countless hours searching for a solution I just wanna burn down the Valve HQ for their stupidity.
