Today, I started ESO from the Launcher to cycle through some characters. When finished with a character, I selected "Log Out" and got the daily-rewards popup (as normal). When I selected "Log out" on the daily-rewards popup, instead of returning to the character log-on screen, the game completely closed (as it does when "Quit" is selected). Thereafter, for each character, I had to restart ESO from the Launcher, as logging-off each character closed ESO.exe.
