When I run a workshop game in Alyx/VR like Return To Rapture (Bioshock/Alyx) it starts out working fine and the Combine and Mutants react to me and attack me.

But for some strange reason, when I go to a next level or re-load a saved game after getting wacked, the Combine and Mutants don't react to my presence and just stand there without any action.

It's weird. I can move around them and even shoot them but they just stand there. After shooting them enough, I actually get the sound of them being killed, like the ring when a Combine is killed, but they still just stand there.

Everything else in the game appears to work fine.

I have a video that shows the exact issue and it's 70MB.

Has anyone ever experienced this issue?

What do you think it may be?

Makes add-in game play really suck.
