I did exactly what several places said to do in(when browsing around the forums) to create a walk cycle. I completed a MOVING cycle, then converted it to an NLA strip and then told it to repeat 10 times. I then set the length to 400 and then set the offset bone.
It still only plays through the walk cycle one time though!
The NLA editor works in two modes, “Action” and “NLA”, which is controlled by LMB’ng on the "HeadLessMan (Action Window Icon) / NLA (“SharkAttack” / NLA Icon) in the left side of the NLA editor beside your “Armature Civ” strip. Click on it to switch to NLA mode and it will work.
In “Action” mode, only the currently selected action will play.
