I'm having a lot of trouble managing the ground planes in my design. It is a 4-layer board, and I'm finding that after some editing, the ground plane on the top layer disappears and has moved to another layer all by itself. When I use the search function (ctrl-f), it is unable to search for ground planes, which makes debugging and fixing more difficult.
