Alfonsocsr,
While you wait for the GMs to respond. There are a few things you could try, just in case you haven't thought of them already.
1) Sell the ammunition upgrades back to the market. Most items can be sold for similar amounts to what they were bought for, this could help you get out of your cash shortage. To do this, select the "Trade" tab drop down menu at the top of the screen. Click "Products in Stock, Buy and Sell". On this page, scroll down to "Ammunition Quality Upgrades" and select "Sell". In the Offered Quantity Box, type the amount you want to sell. Then press the "Place Offer" button.
2) under the "Trade" tab, click "Order Strategy and Quality". Scroll to "Ammunition Quality Upgrades", check it see if you have accidentally set it to automatically order Ammunition Quality Upgrades. If the Low water mark and order quantity boxed are grayed with 0 in each column, for ammo Q, then you're ok. But if there is a number value above 0, it's been set to order automatically.
3) Under the "Army" tab, hover over "Military Units", then select the page "upgrade fighting levels". Check to make sure it hasn't been set to automatically upgrade your army units. On the right hand half of the screen should be a "Ammo Quality" section. This contains options to automatically upgrade your militay. If each military unit has the "Set Target" option grayed, with a value of 120, then you are ok. If it has a number above 120, then it's set to automatically upgrade. In that case, set it back to 120 to stop it trying to upgrade your military.
I hope this helps you. Hopefully your nation is doing well
