Anyone know how to fix this? I have installed the 1.2 patch, and as the Brutii have held Memphis for quite some years, enough to build a Dockyard upgrade, and the city has never had sea trade while I've held it. (Neither the little "boat traffic" graphics nor any sea based imports or exports on the detailed income screen).

I thought the port upgrade would fix the problem but there is still no sea trade in/out of the Memphis port, which sucks because I have now upgraded Thebes with a Dockyard, and Petra and the other port with at least a shipwright, and there are only 4 ports on the Red Sea in the first place, so Memphis is in a perpetual negative trade balance (big population with low trade means it supports a large share of my army with less than its share of trade).
