Is that the same game where the exceptions occured? If that's the case, it's easily possible the calculation was screwed up and the logging also didn't work right anymore.

I have committed a fix now, please report if this kind of error remains in games that were started after the current revision.I seeSorry.
Well, I got this interface from the Blue Marble you designed for DoC btw. I didn't do anything else
Hey Leoreth,
First of all, I want to say I named my Nord stormcloak in Skyrim Leoroth =P. I think it's a good Nordic name that isn't too... Yngvrgysprffy.
Secondly, I tested some more of the civilization, and found yeah, every single civilization I played cannot open world builder after a certain point. (A few turns after spawning). I know you have a lot to do, but perhaps it's another embassy bug?
Also! By can't open, I mean crash to desktop if I try.
It appears you changed the color and the typeface.
