No inputs, no tracking!

[nikita-mordik]

The first time I create a player rig, everything works fine.
But when I delete the rig and later create a new instance, each SteamVR_Behaviour_Pose shows isActive = false and isValid = false, so tracking and movement stop working.
How can I fix this? Is it even possible?

Note:

• no errors apears in console.
• Movement (forward, backward, left, right) still works, but rotation doesn't.
