the actor does not appear to be anywhere.
If it's in the scene before the game starts, you could use the "Poor Man's Debug" method...
Set the Actor's X value to a game attribute
Set the Actor's Y value to another game Attribute
Have the scene display those values on the screen.
I do think something could be screwy with Stencyl though. I've been working on a project that was started with Stencyl 2.x. When I ported it to 3.x, I had problems with the location of displayed text.
