As the title says, my mesh does not deform along with the rigify bones in pose mode, even though the bones are in pose, and not rest position. I have already adjusted the weighting, and I know that in the past, it's worked completely fine. I have no idea as to what caused it, though I believe it has something to do with changing the weights on some of my objects.
In the past versions of Blender, selecting multiple vertices in edit mode during this stage would have crashed the program, though that seems to be fixed in the latest version, giving me some hope that this is a mistake on my part, or a fixable bug.
Below is a screenshot of what the problem is like. I've also attached the .blend file in the link for anyone willing to lend a hand.
