1) Visit http://maps.secondlife.com/secondlife/Main%20Channel%20Sandbox2/128/128/23

and create a landmark saved to your Favorites bar.

2) Teleport to another region and log out.

3) Relog, choosing Main Channel Sandbox 2 as the spawn point from the drop down menu.

4) You will find yourself not at the expected destination but at http://maps.secondlife.com/secondlife/Main%20Channel%20Sandbox2/0/0/23 (at least I have done, ever since installing this update)

5) Log out and choose a destination on the map (e.g. https://maps.secondlife.com/secondlife/Sandbox%20Bricker/128/128/27)

Click to log in. You find yourself (or I do) not at the expected destination but at http://maps.secondlife.com/secondlife/Sandbox%20Bricker/0/0/7

Teleporting with landmarks or the map once logged in works as expected.
