I'm working through my first character modeling class, and having an issue! I hid the main body (anything past the wrist) of my character while in edit mode, to work strictly on the hand. When I went back and unhid the rest of the mesh, I stopped being able to edit the mesh in sculpt mode. I am able to sculpt the hand, but when I click anywhere that was previously hidden, it won't move! At first it wasn't responding in edit mode either, but now that seems to have been resolved after "unhiding" the mesh additional times, even though it was already showing up.
I tried this in Blender 2.90 and 2.91 and neither are working.
Any suggestions? Here is the file: https://www.dropbox.com/s/5uh7100zk0rkqc4/Character%20Modeling%20Tutorial%20DIKKO%20Beth%20Model%20Hand%202.blend?dl=0
Thank you guys in advance!
