We're not sure specifically what changed in update 1.45, and Rockstar didn't immediately return a request for comment, but it looks like the October 16 update allowed mod menu users to target their exploits using unique ID codes from the Rockstar Social Club.

While SnowieLive continued to drop dead for no reason, the troll sent him an in-game chat message-which, again, should be impossible outside of multiplayer modes-taunting, 'Ur not safe in singleplayer.' Later in the stream, the modder wiped out the bank accounts for SnowieLive's single-player campaign save. When SnowieLive restarted in singleplayer mode, he started dropping dead the instant the game started. One of the first examples we saw came from Twitch streamer SnowieLive, who had a cheater interrupt his stream by kicking him out of his session, claiming to be an administrator with GTA: Online's developer, Rockstar Games.

For about 48 hours this week, the cheater's paradise seemed to turn into outright hell for everyone else when game update 1.45 (which consisted entirely of 'General fixes for stability and security') unintentionally allowed cheaters to harass other people, even when those players were in single-player modes.
