Ok, the sent bug has been fixed. Turns out when I switched to this new text entry box I forgot to add in the checkbox for saving a copy of the message. The box is back now, and it works. I've recovered all sent items too. This means anything you sent since 2/28 is automatically in your sent box now. From now on though, you'll be able to uncheck the box if you don't want to keep a copy, for whatever reason.
