Ok, fixed this problem, but I have another. Buttons have targets to multi_manager (mm) and mm triggers relays, which deactivate 5 ambient_generic, and triggers also one ambient to play sound. It's ok, but relays can't be triggered. In-game I'm pressing buttons, and only music is playing, any can't be deactivated.. Even console after command "developer 2" types me firing relay, but nothing is happening with them. What's the problem? I checked entities a lot times, I didn't found any mistake.
