Hey there, It seems that when you activated cross save you chose your Steam account as the primary account rather than your Xbox account. Your Xbox account hasn’t been deleted or anything so don’t worry about that, it has just been placed into temporary storage. Please don’t disable cross save as this will lock you out of activating it again for 90 days. You can fill out the contact form found here and Bungie can change it over for you. https://www.bungie.net/en/Help/Troubleshoot?oid=48099
