Addon Information
Name: Edit Mesh Tools (0, 3, 6)
Author: Meta-Androcto

Short description of error
Using the relax function with objects that share same data will create a new duplicate (with unique data). Also the linked one will then behave as it would have shinkwrap modifier on.

Exact steps for others to reproduce the error

Enable Edit mesh addon
Use Duplicate linked (alt + d) for the default cube
With the new cube go to edit mode and use the "relax" function

Extra note:

Similar behavior with object that has shape key.

Steps to reproduce

Add mesh
Add shape key for it
change shape key value to 1
go edit mode
use relax
