Hi. Seems to be some kinda problem when duplicating roles. This is my test case.
1l) create two folders under your root node, Folder1 and Folder2, for instance.
2) Create a Role called Test 1, for example. Add content -> create and limit this to subtree Folder 1
3) Copy Test 1 role and try to change Folder 1 to Folder 2 in limitation (you will need remove folder1 and folder 2)

The result, copied role results in having no limitations at all while role1 says something like Subtree()...

anyone can confirm this?

Steps to reproduce

Description says it all
