Home City Decks Disappear when Making a 25+ Card Decks

In the original AOE 3 it was possible to edit home cities via text editor and add more cards for home cities above the 25 card limit (up to 44 cards).

That was nice and easy way to mod home city decks for single player Skirmish.

However, when I try to do the same in AOE3 DE that home city deck simply disappears.

Was that done on purpose?

These home cities are good only for single player.
They don’t work for Multiplayer.

So please allow us to mod single player home cities.
