Why immortal failed on Gluth

[jackslammer]

The three people in question HAD commanding shout and it didnt fade until they died.

It doesn't show any of them gaining or refreshing a commanding shout. I guess there could've been a dead zone in between Aragon and Abec that three people didn't get the shout.

Browsing the forums, several guilds are reporting weird behavior with commanding shout and Gluth's decimate.
