Example above. Until I inadvertently did it just now, I did not realize you could move a token off the VTT. As you can see, only a piece of the name badge is showing and nothing is "clickable" to drag it back. I was able to use CTRL+A to select the token and move it back onto the VTT, but I'm not sure if this should be allowed by the VTT in the first place, so I post it here. Hope this helps.
