A 200MB day one patch is in bound for The Crew. As strange as it may sound, the patch fixes a problem that saw some players unable to join a Crew. Nope, we are not kidding and we could have not made this up if we tried.
Beyond that the problems with joining a Crew, the patch fixes a number of other things to improve stability and performance. The patch also activates the Drivehub challenges and the Faction war mode.
