	message = reminder_edit(bot, groupid, last.message['message_id'], newtext,
	last.message.get('caption'))
	records[key] = (last.time, [event.copy() for event in events], message, text,
	suffix)

If editMessageText/editMessageCaption fails, reminder_edit returns None, which gets written into config/daily.pickle, then all future attempts to dereference last.message['message_id'] will fail.

This used to be prevented by simply checking if message is truthy before updating config/daily.pickle:
