Fairy Garden EA app Error - "Game Ownership Disabled or Deleted" | EA Forums - 12331060

For the household you can't load, please open Documents > Electronic Arts > The Sims 4 and delete any lastexception files you see.  Try again to load this household, and when it doesn't work, look for a new lastexception.  If you find one, open the file and delete the first line of text, then attach it to a reply here.  Alternately, you can copy its text and paste it into your reply.

You don't need to wait more than a few minutes to confirm the household isn't loading.
