Delay in saving progress, character, money and vehicles are still a problem.
The day before, I was NOT able to save. Yesterday, I WAS able to save. Today, I was NOT able to save again. That goes my levels and RP.
A check at GTA V Online site says that server in PS3 is up, but there's a small little icon stating that some players are still experiencing issues, and I'm reckoning I'm the 'lucky' one.
My advice to some or if not all, once you load your online game, try doing something (a mission, or buy something, or deposit your money or withdraw) then save it. Once you managed to save, that means you can safely proceed your game. However, if your changes are not saved, that means you are experiencing the problem Rockstar is trying to fix, save your time, and breath, quit online for that few hours.
Hope this helps those like me while waiting for the incompetent Rockstar to fix their forever growing mountains of bugs and issues.
