Folder renames sometimes break

[bctcvai]

If you have a nested folder structure with folders underneath, the children folders become invalid if you rename the top folder.

Reproduction steps:
1.) Create a root folder
2.) Create a folder within the root folder (e.g. SL1)
3.) Create a folder within this folder (e.g. SL2)
4.) Observe Root>SL1>SL2 path is working
5.) Rename Root
6.) Observe Root>SL1 is valid, but SL2 is now orphan'd.
