In the Dopesheet, I had an animation. Now for an unknown reason, the armature bones move but the object does not, LocRotScale wise. While I can perform the steps of moving my object in OBJECT mode, and inserting or replacing a keyframe, it is updating all the keyframes. As if there were no keyframes. I can't keyframe any rotational or positional motion. Armature keyframes are still moving, but all motion associated with the armature itself... it's lost. The keyframes are there, but they're all the same, and I cannot change them.
Here's a video of my screen. https://vimeo.com/298955191
