bombard defense for buildings

[Mace]

If you give a building "bombard defense" (see Editor) then for some reason that structure will NOT show up on the build queue of a City-size or Metro-size settlement...only on a town size...

Is this a new revelation to any of you, or is it old news?

Or am I mistaken?

bump. Well, upon further testing, if you give a building "bombard defense", only Town-size can build that building.

That's why City Walls have bombard defense...and only towns can build them...

And Civil Defense has no bombard defense...and any size city can build them...
