Trade routes/World wonders cost issue

[alpha2929]

After updating to latest SVN and load my good old immense 50 civ save I noticed that some of my cities (La Vega and Barataria) are on starvation.
Further check (see LaVega.png screenshot) revealed that problem may be connected with trade routes.
Also I noticed that some of World Wonders costs enormous amount of food and science (Wonders.png)
I assume that those costs are defect.
My save and user settings are attached as well.

Looks like you hit an overloaded integer somewhere or had some kind of RAM memory location conflict. Those are not the values on those buildings obviously. Trade route calculations did change to diminish their maximum value significantly but nothing quite like that.

I may try the save later.
