A post on the Rockstar Newswire explains that the latest update should prevent any more players losing their characters, rank, apartments or cash. The one thing that you may still lose is your vehicle, but only in certain circumstances.
"A new title update to address the reported issues of game progress loss in GTA Online as well as other technical fixes, tweaks and enhancements is now available for PlayStation 3, and we expect it to be available by tomorrow at the latest for Xbox 360," it reads.
Despite this, Rockstar has reiterated the advice offered last week; Exit GTA Online by returning to Single Player in order to force a save, and do not select "Retry" or create a temporary character when confronted with a message saying the Rockstar Cloud Servers are down.
The developer added it's continuing to investigate what caused the loss of characters as well as what can be done about it. As of right now, it isn't clear whether lost characters can be restored or if compensation will be coming.
