At 10am PT/1pm ET today, Bungie will be releasing Destiny update 2.4.0.1 and 2.4.0.2 on PlayStation 4 and Xbox One as hotfixes. “After Hotfix 2.4.0.1 and 2.4.0.2 become available for download, the PlayStation 4 or Xbox One consoles may remove players from Destiny to download and install the updates either immediately or after players return to orbit at the end of their current activity,” Bungie adds. You may also receive the CAT error code when this happens.
Both Hotfix 2.4.0.1 and 2.4.0.2 will need to be fully downloaded and installed before you can log back in to Destiny, and the hotfixes may “download and install as a single update or in close succession to each other.” These latest updates are being made as final preparation for the Rise of Iron expansion, which will be available at 2am PT/5am ET/9am UTC on September 20.
