**Short description of error**
Blender lost my character object
**Exact steps for others to reproduce the error**
I was modeling a character, I rigged it, but I needed to improve the mesh after rigging. Then I started to configure the materials. To be easier, I created Vertex Groups, to select easily and apply materials. Before quitting, I've hidden the Armature.
Another day, when I've opened the file, I got the error "Lib: Object lost from scene: 'Scene'". The last thing I was doing is applying material by vertex groups.
Is there any way to recover the object or I have to start it again? I was almost finishing my work.
