Following the patch released earlier this month for fixes, Bethesda has released The Elder Scrolls Online update 2.16 April 21 patch today, while the game is undergoing maintenance!

The Elder Scrolls Online Update 2.16 April 21 Patch Notes:

Note: The stuff listed below are from the PC version’s latest title update, which is what the PS4 and Xbox versions are most likely getting today as well. We’ll update the post once Bethesda clarifies this later in the day.

The Elder Scrolls Online v6.3.8 fixes the issue with players on your friends or guild list displaying their last logged in date of 1970, a few fixes for Gamepad Mode and some base game quests, resource nodes not appearing correctly, and more. This patch also fixes the issue where some NPCs were invisible or not respawning in some zones. The size of this patch is approximately 91.6MB.

• Fixed a calculation error in the Rationer star’s effect.
• Updated the Rationer Champion Star to only provide a duration bonus to stat-altering foods and drinks. This Champion Star was never intended to affect the duration of such foods and drinks.
