When using pet food without having a pet alive it almost freezes the client. Skills stop working, some portals can't be accessed, Trade button don't work, Cash Shop button stops working. Double clicking pet food doesn't consume it but causes these problems. This is easily fixed with the simple use of a potion, still a bug.
Not sure what is causing this, but I do know it is related to the bug which causes pets not saving fullness, name, etc.
