I see, though all my expenses haven't been factored into that figure if its so, and I find it hard to believe I could have taken a 13 billion hit to my total production unless GDP is being treated as available funds. Maybe he just hasn't counted the trade I did with you yet?
But even then there's inconsistencies.. Though I'll put that down to the rebuilding of the villages. 
The figures for me stumped, looks like I'm gonna have to wait for Gowia to clear up what's going in, because I think I may be achieving Weimar levels of economic volatility xD
