alice-teacher Missing object

[EDIMEK PETER]

Good day all!
I was working on an animation yesterday night and I got to arranging my
object tree. I mistakenly pulled an object into a wrong group. When I
realised the mistake, I expanded the group in order to move the object out.
But to my surprise,  it wasnt there. Am confused. How can I rectify the
error.
Attached are the screen shots of the error
