Question: I'm having problems with certain features and stats on Social Club -- does Rockstar know about this?

Answer: Note that many of these legacy issues only occurred on the old Social Club site (before 5/6/12).  We will be revising this list soon after the new Social club launch to see which, if any, of these issues are still occurring.

Website

• Problems with the friends system
• Issues with trophy and case data from L.A. Noire synching to website (Reports of not synching include: Platinum, City of Angels, Auto Fanatic Progress, Lead Foot, The Hunch, Star Map. Reports of not unlocking include: The Moose, The Brass, Public Menace)
• Problems with Social Club "standing" display on site
• Incorrect website XP values for some challenges, such as Repeated Killer headshots and Double Death Dealer headshots
• Beaterator showing up as linked, despite not having played the game
• Other general issues with stats not synching to to Social Club

Red Dead Redemption

• Not getting checkmarks for completing RDR challenges
• Social Club challenge times in RDR not uploading to Leaderboards
• "Oops, an unknown error occurred" when claiming RDR cheats

L.A. Noire

• L.A. Noire Rank 20 not synching to Social Club even when it says Rank 20 in game.
• Certain trophies not synching, or trophies synching while none of the in-game stats sync

• Problems with Bulletproof Patriot synching

• Base Jumping leaderboards not updating properly
• Problems with GTA IV race time and event completion times synching and staying synched to leaderboards
• Invalid GTA IV times being submitted from the game and occupying top positions on leaderboards
• Money/stats shown in-game and in lobby differing from money/stats shown on leaderboards
• Stats generated during gameplay occasionally not synching to leaderboards
• Videos not uploading properly to Social Club TV

Midnight Club: Los Angeles

• Problems with accessing MCLA Social Club features after changing Gamertags 
• Occasional problems with Driving Test progress that requires re-linking the Social Club account with the platform account and then forcing saves to resume progress toward the Audi R8.

We are hard at work on these issues and will update this article as soon as there are new developments.
