The latest update for GTA Online, 1.05, is now live on both Xbox 360 and PlayStation 3. The patch fixes "residual issues" such as players occasionally losing vehicles or modifications due to cloud save failure.
In the same Newswire post, Rockstar confirmed that anticipated Stimulus Package - compensation for gamers who experienced problems during the early stages of GTA Online - is set to be distributed in the couple of days following the release of the 1.05 Update.
