1. The two weeks thing is ridiculous. If those fighting NPO couldn't stagger them even with multiple chances then NPO shouldn't cut their work out for them.
2. In regards to stunting growth either
a. The reparations should be much higher. I'm thinking 400k tech and $24 mil or disallow intra-alliance aid.
or
b. Have all NPO members go without factories or labor camps. This does not hurt those who fought as much as it does those who stayed in peace. Perhaps 0 soldiers is another option.
