Code:
    verb
        Create_Unit() // Create a unit
            var/Unit/NU = new()
            NU.Commander = src
            NU.ID = ++src.LastUnit
            src.ActiveUnit = NU

        Save_Unit() // Saves Units
            src.EditMode = 0
            src.ActiveUnit = null
            src.Units += src.ActiveUnit
            for(var/mob/M in src.client.screen)
                src.client.screen -= M

        Delete_Unit(ID as num) // Delete a unit
            for(var/Unit/A in src.Units)
                if(A.ID == ID)
                    A.Disband()
            return

    verb
        Edit_Units() // Allows player to edit units
            if(length(usr.Units) <= 0)
                src.EditMode = 1
                src.Create_Unit()
                src << output("Creating Unit","UnitForm.Chat")

            else
                var/L = list()
                for(var/Unit/U in src.Units)
                    L += "[U.ID]"
                L += "New Unit"
                var/X = input(src,"Which Unit would you like to edit?","EDIT UNIT") in L
                var/Unit/UNIT
                for(var/Unit/U in src.Units)
                    if(U.ID == "[X]")
                        UNIT = U
                        break
                if(isnull(UNIT))
                    src.Create_Unit()
                else
                    src.ActiveUnit = UNIT
                return


Problem description:
For some reason, the input list doesn't appear. Here are the steps I go through to get it up.

1. Run Edit_Unit() for the first time.
2. Save_Units()
3. Run Edit_Unit() again.

My debugging statement tells me that the else in Edit_Unit() is reached after the save. I figure at the very least, "New Unit" should be in the list but it doesn't appear at all.

Have you tried outputting the contents of the list to see what it contains?

Hmmm. Outputting the list shows me that there is only one thing in the list: New Unit. I'm guessing that means I default to the New Unit option.

Pretty much.
Stuff isn't being added to the list.
