So I've been making a human model in blender from scratch. While I was working on the hands, I've suddenly been unable to move, rotate or scale the rest of the mesh. I've seen suggestions that the Transform options need to be unchecked, which has been the case. I'm having trouble finding any other potential solutions, since my issue only cause a majority of my mesh to be unmovable. I am able to move the object as a whole around in object mode, but that's it. An example of this is when I go into edit mode and select the entire mesh and try to move it around. Only the unfixed portion of the hand moves, everything else is stationary. I can't sculpt on those fixed portions either. None of this was an issue a couple days ago when I modeling the rest of the body, but now it's suddenly a problem.
I appreciate any help I can get to solve this issue.
