Unfortunately we've encountered a bug with the loot fairy when they are hanging out in every adventure, as should be happening for our birthday weekend. We've turned the loot fairy off for the moment so that it just appears in the regular location, but are working a fix for this right now and hope to have the fairy back around soon. Sorry for any disappointment this may have caused. I'll update this thread when things are put right.
The server is back up now and the loot fairy should be restored. Hopefully we won't see any more stability issues...
