Armature animation not working

After altering the leg rig of a character, we’ve found that the keframed armature animation is no longer working.

Deleting then adding new keys doesn’t fix this. The camera in the scene will animate just fine.

I am thinking: is there perhaps a disable keyframed armature animation button somewhere that I do not know about?

Thanks for looking,

Ok so I rebuilt the rig. It deforms the mesh just fine, but still none of the keyframes are working. Its mesh just stays posed in place at whatever was the last position it was posed to.

Anyone got any ideas about this?

Just downloaded the newest blender version and the problem shows up there too. Will I need to rebuild this character from scratch?

Had to rebuild rig from scratch. Nevermind.
