How can I restore my single-player game progress in GTA5 after an online game wiped out my saves?
This was a bug in GTA online that caused Story Mode save files to become corrupted when switching from Online to Story. There has been a title update to fix this.
It won't restore your character, but Rockstar is giving everyone who played online during the age of strife(October) $500,000 in in-game cash for their online characters
