Grand Theft Auto 5's online portion has been patched once again for PlayStation 3 and Xbox 360, with Rockstar hoping this latest patch will fix up issues relating to player characters being deleted at random.
"This title update will resolve the cause of players losing their gameplay progress except for some specific instances where players purchase a vehicle and the save does not occur due to a cloud save failure. A fix for that particular issue is being worked on and we will provide an update as soon as we know when this will be resolved."
Rockstar also recommend that players "save your game before leaving GTA Online, otherwise you may lose any progress since your last save – this can be done by exiting back to Single Player through the pause menu." Hopefully the issue sorts itself out after this patch, but if at any point you receive the message “Rockstar Cloud Servers are unavailable”, avoid hitting the "Retry" option or create a temporary Character to play GTA Online, as this can cause your previous characters to be deleted. It is instead recommended to go back to Grand Theft Auto 5's single-player and try again through the start menu.
