I am sure you had heard someone say in group “My foods gone how do I get it back?” We had several helpers and CSRs say MOOG it. This is something we have been trying to track down and while it was impossible to reproduce we do think we found the cause.  The update should prevent a dish from going poof in the future if your sim runs out of URLs.  However you may still get the warning that the sim is out of URLs and it is a good indication that your sim needs a restart.  If you have food out that is an older version this is fine you may leave it as is the food will still be eaten. If however you rerezz said dish it will poof asking you to MOOG a current version.

Current Food version for all but the Happy Teddies in all animals is 2.7.3 in Happy Teddies it is 4.1.1
