title: OnFormSubmit trigger issue
body: <p>I have a number of forms that have all been working fine for several months (and years in a few cases).  We're a small school district and I am the only tech.  I built the forms so that teachers can request equipment, ask for help, or ask general questions.  The form is embedded in a google site shared with staff members. Once they submit, an apps script in each spreadsheet collects the form data and emails it to me, so that I do not necessarily have to look it up in the spreadsheet.  This has all worked fine for a long time.  Beginning in the last few days I have been getting error messages (example below), and it appears my onformsubmit triggers have all been lost.</p>
  
  <pre><code>function onMyFormSubmit(e) {
    var myEmailAddress =  "aUser@mydomain.com" ;
    var myEmailSubject  = "Ask The Tech" ; 
    var replyToAddress = String(e.namedValues['Username']);
    try{
      var message = e.values.join( "][" );
      var hmessage  = "&lt;b&gt;From: &lt;/b&gt;" + replyToAddress + "&lt;br&gt;";
          hmessage += "&lt;b&gt;Question: &lt;/b&gt;" + e.namedValues['Your Question'] + "&lt;br&gt;";
          hmessage += "&lt;b&gt;When: &lt;/b&gt;" + e.namedValues['Timestamp'] + "&lt;br&gt;";
      var advancedArgs = {htmlBody:hmessage,replyTo:replyToAddress};
      MailApp.sendEmail(myEmailAddress, myEmailSubject, message, advancedArgs)  ;
    }
    catch(err){
      MailApp.sendEmail(myEmailAddress, myEmailSubject, err)  ;   
    }
  }
  </code></pre>

  <pre><code>Start   Function    Error Message   Trigger End

  </code></pre>
  
  <p>As you can see from the example script, none of the scripts directly call getActiveSpreadSheet, so I don't understand why I am getting this message.  Additionally, once I looked at the script, and realized the triggers were gone, when I added a new trigger, the script started working again onformsubmit, however I STILL get the error messages delivered to my mailbox, as well as the script-generated email.</p>
  
  <p>Is this issue related to the recent forms revamp, something deficient in my code, or is there anything I can do about it?  If it's a google bug, is there an issue tracker I should submit my problem to? Thanks in advance for any responses!</p>
