“Self-Recursive” AppData folder causing RoboCopy to freak out

问题

I use RoboCopy to perform a daily backup script using Windows batch. about a week ago I noticed that RoboCopy detects one path as "too long" see att. image

Obviously, this folder path does not exist. But for some reason I have an "Application Data" system folder inside my AppData\Local, which is a shortcut to itself (i.e the AppData\Local path).

This seems to be what is causing RoboCopy to interpret a folder path as AppData\Local\Application Data\Application Data\Application Data\Application Data\Application Data\Application Data\Application Data\Application Data\ etc

• My questions are:
  1. How could this system folder have appeared?
  2. Is it safe to simply remove the "faulty" folder link?
