Dear AC followers, we are encountering an unknown and unpredictable issue that causes random crashes with single-player race events, probably due to some additional implementations that single-player thread shares with the multiplayer build. We are working to identify the cause and to solve it, but we can't commit the new build within today. We apologise for this inconvenient, we'll keep you informed as soon as our development team will be able to make the new build available, hopefully within tomorrow.
Thank you for your patience and your kind support.
