I have made this low-poly character mesh, and so far added bones from the torso to the head.

So, my next step is to add the legs. Unfortunately, when I extrude from the torso bone to the top of the legs, the hip/leg bones don't parent to the torso bone. When I move the torso, the legs just stay totally still and they disconnect from the torso.

Even when I parent the bones manually, both in offset and connected mode, the torso simply does not move the leg/hip bones. It does move the others though. This is a re-rig of an old model I made, and I did not have this problem, but i don't remember exactly what I did so I'm not sure if I'm forgetting something. This leads me to believe that there might be a parent limit on bones, but I highly doubt it. Does anyone know a solution to this?
