I have been noticing this happen occasionally; I'll see a random point/vertex detached or close to my mesh that is connected to the mesh(far left orange dot). If I delete it, it will erase my mesh and if I want to manipulate the object, it totally starts to deform/mess with it as shown below. Anyone else have this issue/ know why this is happening? It's probably a newbie mistake but can't seem to understand. Thank you!
