Rigged mesh deformed after opening blend file I have a linked object in a master file. I then create a proxy of the rig, and everything works as expected, I then save and close the file. 



But when returning to the master file, the mesh is completely deformed. 



If I put the armature in 'Rest Position' or remove the armature modifier and re-rig the object from scratch, I no longer get the problem. 

The object in the linked file has scale and rotation applied, and the armature seems fine as well (using rigify). I'm new to working on a large scale project and using linked objects, so is it possible a step could have been missed, or if this could be a bug? (Using Blender 2.78c)
As Firewill noted, it is a standard problem with python scripts. By default, Blender disables running scripts from scene, because downloaded scripts may contents malware.   

So, to run this scripts you mast press "Reload trusted" in header of window, to confirm that blender may trust scripts:



If for some reason, you haven't this buttons, there is a workaround: Open User Preferences, in File tab click auto run python scripts:



In this case it is recommended to add a downloads path as Excluded.
