I have a file with 13 components. The 13th component in the list vanishes if I try to edit the sketch in the 12th component.

I have a project with 13 components nested under the top component in a file. The 13th component in the list vanishes if I try to edit the sketch in the 12th component.  All of the components have just one simple sketch with circles and squares.  Maybe 3 to 6 circles and squares in each sketch.  

So I am going to try to move some of to a different editable file if that is what you call it.  Will that fix the problem?   Anyway I will find out.  When you have the ***editable/read only*** button is that what is called a file?

Yes, this behavior is expected, assuming that the components are all local to a single design.  Sketch edit "rolls back" the timeline to the time when the sketch was created.

Yes, moving Component13 to a separate design (external component), will solve this "problem" (which is not a problem), because its timeline will be in a different design.

OK wow that was not expected to be so easy,  thanks.  That means my method of laying this out is somehow wrong. So I need to rethink how I do this.   What I was doing was just putting my parts together in one file.   For example this is a plasma cutter project.  And I have a few holes that need to be cut to put the pieces in the holes.  So for a LED panel mount,  I needed the size of the threads to cut a hole for mounting the LED.  And the size of the bigger part of the LED to see how it fits, so a circle inside of a circle.  And then the hexagon nut to hold the LED to the panel.  So those three are all I need for the LED.  The hole (circle) for the threads are normal lines,  and the other 2 just need to be construction lines so I can see how it fits. 

But back to the question of what I did wrong.  Since I don't need a timeline for this extremely simple parts file, should I delete the timeline?  This is basically my parts file.  Nothing is put together in this file.  Basically it could be a template for the parts to be assembled in my assembly file,  when I get to that point which I am very close.  So without the timeline would this behavior of deleting my 13th component stop?  Not sure how to delete the timeline either.
