This one was a headache and a half.

The usual - check your stats. If things seem a little off, remember that land transfers can lead to loss (or gain, if you are receiving) of resource level, industry level, infrastructure level, and of course, population. Decided to do away with waiting for a year before updating the stats - it was more realistic, but a bigger workload for me.

And which one of you was the idiot who decided to give almost all the of the land in North America to three blue nations?
