[AR] Where is the world origin set

Hi there, developing for the magic leap and this isn’t a similar question to my other post but applies to all AR in general.

Where is the world origin set.

For my app we have the normal startup, where I have a world origin actor refreshing its position to identity on tick for debug purposes, when it starts its at device boot location.

However if I host/join a lobby and go into a different map, the origin shifts.

Was wondering what was going on, whether its just happening on the leap or others have observed this.
