The missing address fields according my Webmaster mode is from customer/main/register_address_fields.tpl - see Alex's code below (from page 1 of this thread).

with this:

{include file="customer/main/register_address_info.tpl" need_address_info='Y'}

2. add corresponding smarty assign statement in "include/register.php" script.

PHP Code:

$smarty->assign('address_fields', $address_fields); 


I don't see this file in your list of modified files.

Sounds like you missed this one or you applied to just the common files.
If you are using a custom skin (e.g. Ideal Responsive) you need to make the change to

ideal_responsive/customer/main/register_address_fields.tpl

Any other skin changes in the code mentioned also need to be made to your custom skin files (if they exist), not just common files.

I just registered a test customer on my site and can confirm the code does work properly in 4.6.3.

Hope it helps.
