I've an object with edges that appear to be connected to a face, but when you move a faces touching the edge, it leaves a hole in the object:
I would expect the top and side faces to 'stretch' with the selected edge, when I move the selected edge (just like the bottom one).
This shape started out as a cube. I used only 'subdivide', moved edges to where I wanted them to be and tried the 'edge split' modifier. (what did I (likely) do wrong to create this mess?)
My question is: How do I repair the object?
