How do I build from upgraded ship designs? (version 1.2.4)

[Vholes]

AU:D 1.2.4 campaign.

I hope I'm missing something obvious...

In my current campaign game I'm Austria-Hungary (1890) with the Ottoman Empire as a minor ally, with them ordering my ship designs to be built in my shipyard.

The Ottomans have been ordering upgraded designs of my ships, say a TB Python (1892), which my shipyards immediately start building.

When _I_ try building Pythons, I can't build the 1892 upgrade, only the 1890 original and then upgrade to Python (1892) later on.

Am I meant to be able to directly build ship upgrades?  Am I forced to duplicate the Python (1892) design to build it?

Why can my shipyard build upgraded designs for the Ottomans but not for me?

Is there a way for me to build the upgraded designs?  The build button always is greyed out...

Sorry, that should have been "UA:D", doh!

yes you have to make a copy of the design to be able to build it

Thanks for the reply.  I just find it an unjustifiable restriction, looking all the more stupid for my shipyards building Python (1892) for the Ottomans.

They should fix this because it is really anoying. And please let us build obsolete hull.
