Knock on wood, but I haven't had any problems with lost characters in weeks now, and data has been saving fine for the last week. The only thing that still seems to have problems is matchmaking and getting people into your lobby. Hopefully the lack of problems now means that they are just about ready to release the stimulus.
Happened to me twice last night. Played before dinner and when I got on afterwards everything was gone. Played again last night and bought an apartment. Checked my stats today and I lost all the rp and cash I earned last night. I've lost count how many times this has happened now. I'm starting to get pissed off.
Just thought I should let you guys know that my stats finally updated today. I didn't play yesterday and I just checked to see where my stats were at and my lvl 33 is back, my money is back, and my tattoos and clothes I bought for my character are back. Still pretty lame that it happened, so I hope they fix it soon.
