Regretfully this doesn’t help as the actor’s location is set correctly - the actor changes position which is reflected in its coordinates and the cube I set as its root also jumps to the correct spot. The problem is that the widget doesn’t come with it if it has to cross the cylinder’s boundaries 
Right now I have a hacky solution where the widget is always inside the cylinder, just facing the transparent side up so that the player would never see it - and it works 100% of the time. If I wanted to put it outside the cylindrical game space though - the cube (its root) will teleport but the widget component will be nowhere to be seen…
