VR Expansion Plugin

Hi, !
I have question about VR character movement working.
There is Actor Transform which is RootComponent transform of every actor. But in case of plugin Root Component (VRRootComponent transform is HMD offset in virtual room) moved out from actual ActorTransform, and ActorTransform is virtual room coordinates, isn’t it?
If I moves to something collision, the VR room will be got an offset in UE world.
But there are more cases when offset occurs. Sometimes ActorLocation moved out from his start point while map is loading (throws in different directions).
Also there is case when HMD turned off, the ActorTransform will also be changed with VR Root Component.
And other implicit cases moves the VRRootComponent. How can I solve ?
