Bug Description: Not sure if it's an expected behavior. See the screenshots. I had a struct with __base() that is inheriting a bunch of fields, and I wanted to create the fields that don't already exist (the __offset* ones). Instead of only creating the fields for the __offset*, it also overrode the fields that already existed.

I created a database that can be used to reproduce this issue. Press S on var_38 and we can see all of the fields get redefined, including those inherited from the base class.
