For Honor developer Ubisoft Montreal has been tracking an uptick in the number of stability problems the game has run into since the release of the Xbox One March update.
The most recent Xbox One firmware update has resulted in some stability problems in For Honor, so Ubisoft disabled some features until it investigates.
These stability issues only popped up on Xbox One, and Ubisoft is not quite sure exactly what this recent update changed to affect the game in this way.
This update added native Beam support, Game DVR improvements, changes to the Guide, and a speed boost to the entire OS.
