Messages sometimes disappear when sending

[Zachary Igielman]

Using a N4 with stable (OTA-5).

Sometimes, when I send a text message, the message disappears from the text box as if it is sending, however it does not appear in the conversation or send. It simply disappears! This means, on occasion (not all the time, and with no pattern it seems), my messages disappear rather than sending when using the messages app. Also, sometimes when my messages fail to send, and I press the resend button, the message disappears and does not re-appear or send.
