AS is crashing for me when I play an Artist where all the info (nfos) is already stored (on my nas), when changing the Storage option for the info to the addon folder it works fine.

I honestly can't even figure out how that error is being generated.  There's a file missing that the addon is expecting to be there, but I explicitly check to see if it exists before moving to the place where you are getting the crash.  If you're getting the error when trying to store the files on your NAS but not your local storage, I feel like it might be a permissions issue on the NAS.
