Hello! Was searching through all the Internet and didn’t succeed 
The key problem is that my Widget Component doesn’t follow an actor which simulates physics (pic1). I have the main “parent” actor for my items where the widget code is implemented (pic2, pic3). I was printing the location of ‘default scene root’ of my “Parent” while playing and it doesn’t change, although the actor was moving… And it doesn’t change when I’m reentering ‘interaction range’. What am I doing wrong? Thank you in advance!
I am still searching for an answer
Still unresolved 
Make sure it’s not attached to the DefaultSceneRoot, that doesn’t move. Try using the location of the mesh or whatever you have that’s simulating physics inside the actor.
It would be a lot easier to just have the widget component setup on the actor by default, instead of spawning and attaching it. On event you could just toggle the visibility and set the text
