The Case of the Disappearing Bone

So, I was going through my old mesh, trying to rerig it because I hated the old rig, and it’s going well. Weight painting, weight painting, finally, I get to my legs and whoa, what the hell, one is missing! LowerLeg.L seems to disappear when in Object/Pose mode, but it’s there in edit. Any ideas?

I can’t reproduce this with the .blend you provided. Have you tried appending everything into a clean file?

Hm, no, but the bone is completely gone when I reopen the file… I will try that.

Even when I append the file, the bone is gone.

I can’t see any missing bones in that file.

How very odd. I’ll just remake the bone.
