All my savegames that are on october or more(game time) were corrupted, I deleted them all and started a fresh game, and the same thing happened again. Right now its impossible to load a game that is on october or more, you either get the "time stop" bug or a plain CTD, depending on the loading method(main menu or in-game menu).
Just for the sake of testing, I saved a game on September 30, waited without doing nothing until October 1 and saved again, but the bug persists.
Im playing V15.1 btw.
