"No Rent Items will no longer be immediately deleted from your character inventory upon disconnection with the server. If you are disconnected from the servers, or even if you log out, your No Rent items (such as summoned food and water) will remain on your character as long as you log back to that character within 30 minutes. After thirty minutes those No Rent items will be deleted. There may be some extreme cases beyond our control (such as hardware failures) where No Rent items will not be on your character even if you log back in within the 30 minute timeframe. No reimbursement will be given for No Rent items lost in this manner."
