Players of Elder Scrolls Online: Tamriel Unlimited now have the ability to change their account name in the account management settings.
Warning: Add-ons store information based on your @username and will break when the name changes. You will have to update the LUA files in your SavedVariables folder manually or using an automation tool.
In case you missed the official notice, if you were affected by the guild bank bug when Orsinium went live, all you need to do is put your stuff in the guild bank before Monday’s maintenance.
Missing Guild Bank Items: For anyone that lost items from stacks of 200 in the guild bank, your missing items will be reimbursed during Monday’s maintenance. You won’t need to do anything, as the items will appear in your guild bank after maintenance is complete. The only action you’ll need to take is in the event you’ve removed an entire stack of an affected item into your personal inventory or personal bank. All you’ll need to do is move it back into the guild bank sometime before Monday. For anyone that erroneously received more items in their guild bank and currently has stacks over 200, consider it a gift.
