Re: New file found.

I think EuphorialQueen is correct. 

I should add, though, that I don't recommend deleting files like localthumbcache or avatarcache unless you're troubleshooting issues or want to start fresh, because deleting them just means the game has to download/generate those avatars and thumbnails again.

If for some reason cache files like that are causing issues, that would likely be a bug.
