EDIT - Nevermind.  Found another post.  Apparently in 10.3.1 you cant copy sub-processes with timer events.  Seems to cause a problem.  I deleted the timers and it seems to be able to work.  You can delete this question.

So we have someone using Forms 10.3.1.635.  We have a large forms process in development and are attempting to use Sub Processes to make it manageable. 

The process saves fine, however if I copy the sub process (which I want to because the next one is similar) the process does not Save.  I clck Save and the icon just says "Saving" but never completes.  I have waited almost 10 minutes.  If I hit refresh the page reloads back to before the sub process was copied.  I can hit Save and it works but again if I copy the sub process I cannot seem to save.  No errors in the logs that I see.  Anything I am missing?  The sub process has ~14 activites, 4 gateways, and some timers.
