However,
I still think you keep trying to patch gaps instead of solving from root.
Negative resources quantities HAS NOTHING TO DO WITH GAME CASH.
Take a look at my main on White Giant (The Punisher).
Currently I have a negative quantity of Military Services of -20,777,934,465.
Where the surplus for such product is......
-13,200,691,548
Yeah I know, my country demands more quantity than the world as a whole can offer, I rock hahaha, no, really it sucks and something is wrong.
"The Punisher" has more than 6T in cash for weeks already and I still have negative numbers on Military Services.
The same was happening with Aircraft Fuel... and it got solved only when I dismantle around 300 Air Transport Units.
Point is, if I happen to have negative Cash on this country, you will start (starting April 17) to sell our weapons THINKING that it will solve this issue WHILE IT WILL NOT.
Don't misunderstood me, though. I do not dislike this feature as a whole, I just think it needs a severe update on it's scope before it's installed.
There is an issue behind this you must solve before implementing something like this.
And on the same path, it is not fair who has been stocking up batteries/ammo for real years to see them gone for not fixed bugs. Even if Steve use them on me :D, It's still not fair though.
Give us the availability to choose whether to sell goods or weapons + add a limit on negative game cash when this auto-sell feature begins.
