I've created a rigged model and created and grouped the model and rig.
I would like to add it multiple times in a single scene. I used File > Append selected the group, made it local L and created a proxy Ctrl + Alt + P.
But I can do this only once, when I try to repeat the procedure described before nothing happens.
It works when I save the group in another file, and link two different groups into the scene.
What am I doing wrong?
