EA/DICE have identified rental time issues with the Battlefield 4 Rent-a-Server Program release on Xbox One and have temporarily removed the feature (death shield fix) as they investigate into the issues.
The servers which were already rented will still be available for play, but admins may not be able to access all the management features at this time. As soon as a fix is in place we will announce its availability. If you rented any servers on Xbox One and are experiencing issues please contact EA Customer Support at http://help.ea.com.
We’d also like to inform you that with today’s server update, we are deploying a fix for the issue being referred to as “Death Shield,” where an invisible “shield” would appear around killed enemies, blocking weapons fire. Thank you for being patient as we worked to get this resolved.
