EA Sports released a big new patch for Madden NFL 18 this week that added new features and made tweaks and changes to the game's various modes. One of the topline priorities was to address the lag in the Franchise mode. As it turns out, this patch actually made things worse in this department for some, and now EA has put out another patch that removes the earlier fix.

So it's back to where things were before, but EA is has pledged to continue to work on the problem until it's resolved. "We will keep working diligently to get the lag issue addressed in an upcoming title update. Issues like this have been, and will remain, our top priority," the developer said.
