I noticed several SendEmail actions that involved sending attachments didn't actually have their attachments this AM. It seems like an intermittent issue b/c I performed the exact same action just now and all emails had their attachments.
I just wanted to note that on the forum in case anyone else experienced this issue using custom SendEmail actions. My company uses them a lot during the day.
I also wanted Method techs to be aware of the issue on the forum in case this information offers any help in fixing the Invalid Viewstate issue they we've been suffering from on the site since yesterday morning (it's still an issue right now as well).
