Minor oversight, but it appears that a recent update had caused a texture effect for one of my triggered abilities to display a checkerboard texture instead of the correct one. Since i do not own Ashes of Malmouth yet, this lead me to believe that it may have been an accidental preclusion of a texture when an update is issued.

Attached is a screenshot of the anomaly in action. I am playing as a Commando.

Yep, I noticed that too. And the hotfix for that dropped just today with a patch. So it should all look fine again.
