first of all, thank you for giving your support with your purchases.
You are looking for right: the Metal ladder is available and it is a free Add-On to Barricades Basic Set and Platforms Set.
Free Add-Ons are released after the main model they refer to and they are available into Download Section of this site. To have the access granted I need to include your Membership to a special Group and I have actually to do it manually at this stage. Generally this operation requires me to check the system and see the new sales (this happens several times a day but for nightly purchases the day after).
I sent you an email to confirm this. Now you can access to the restricted section and download the Ladder.
Surely I need to make this procedure automatic or to include directly the Free Add-Ons on each main models.
Thank you again, Claudio:)
