The daily server reset is very annoying, and I don't believe Sony has actually owned up to why it's every day? I would suspect that there may be some issues with the Server Hardware, or possibly the server code, so restarting the servers each day ensures that there are not any catastrophic or less severe failures that could cause the game to be partially or completely unplayable. This reset also let's Sony do these Mini-Patches or Hot Fixes every day if nessessary. By allowing us to Offline sell out of our House Vault is an awesome Idea as many times I have Vendor mode up when the Server Reset is done
