After update to the most recent version I receive an Error 500:

+++++++
500: Internal Server Error - Class "LimeSurvey\Helpers\Update\Update_470" not found
An internal error occurred while the Web server was processing your request.
Please contact [xxx, my insertion] to report this problem.

Does anyone know where to find this helper?

Looking through my files on the server, I did find something:

/application/helpers/update/updates/Update_470.php does exist, but it has 0 bytes.

Error disappeared after I reloaded this file from a previous version. Strange that this can happen.
