I need to move/resize the artwork which includes an opacity masked object, in which both the mask and the object being masked are different Gradient Mesh objects.
In the Transparency panel, no matter if the mask and the object have the link icon between them turned on or off, moving them simultaneously simply does not work, it only moves one of the two, not both. Of course I make sure to Select All prior to moving.
In my Preferences I tried both checking and unchecking 'Object Selection by Path Only'. The only way to circumvent this is to turn every such opacity masked mesh object into a Symbol. Not very elegant solution though.
Edit: Confirming it is a local issue on CS6 and it occurs exclusively if the object that is being masked is a mesh object. The issue can be circumvented by simply turning the mesh object into a group prior to masking it. Edited the question title.
