Why doesn't my country buy Fortifications?

I have a corp that builds Defensive Fortifications.
I also have a slave country that needs Defensive Fortifications.
I set the corp to offer a contract to that country, and to hold 2 pieces in reserve for that contract. I also made the country order Defensive Fortifications via the Materials page.
But no transaction ever took place, even though the corp actually has the product in reserve. It's just sitting there, waiting to be shipped, but nothing happens.
What am I doing wrong?

How many forts in that slave country now? This could be part of a bug fix either way though.

Did you fulfill the contract by 'accepting' it from the slave?

There are 8 forts; as many as yesterday.

The slave country never received a message or any option to accept or decline the contract. I guess it's supposed to accept automatically, since I own both the corp and the country. When I look at the corp, it appears that the contract is in effect, and not pending.

This is really weird. I set up another contract. My main country received a message about it, and both the old and the new contract proposals are listed under my main country's "accept or cancel corporation contracts".
But when I log into my slave country, no contracts are visible. I double checked to see if I misspelled my slave country's name, but there was no error.
In short: Contracts between one country's corps and another country are sent, but are never received. Must be a bug.

Problem solved. I was looking at the wrong page.
I should have looked under "country contracts" rather than "corporation contracts". Silly me.
