We are aware of an issue with setting online/offline status and working on a fix for future incremental patch. As a workaround, you can swap to Gamepad Mode to set your online/offline status, or click a few pixels below the dropdown arrow to access the menu. For further updates regarding known issues after Update 41, please see the thread linked below.
It's messed up for me too, but I found a spot a few millimeters below the selection arrow that got the status options to light up then I could change my status. It's like the actual selection arrow got moved to a location not exactly where the selection arrow is pictured.
Same issue here the fix as pointed out by a friend of mine on the night of Update41 was to either go slightly above the arrow where you toggle your online/offline status,or even slightly below the same arrow for it to work.
This should never have made it to the live servers,obviously it wasn't tested out correctly before release.
Many addons are broke,along with many other issues that all go to remain unfixed for endless amounts of time.
For anyone that is stuck in Offline-Mode, or simply wants to change from offline to online. or vice versa.
Found a solution and it works.
