Market situation situation?

holy heck... seems like every project save maybe 10 are full red situation?

is something wrong with the game or?

Not something wrong with the game, no. Some products will be in flux, others will more or less always be in the red. In the red is good for you, it means that those items are in high demand and you can make a profit if you produce those items.

Most natural resources tend to be in the high negatives and are the most profitable, but will eventually run out.

To avoid some serious shortages, like factory and asset maintenance, I have my Country buy those either from contracts in my Common Market or my Enterprise.

Shortages come and go.
after the introduction of natural resources we had a period with oversupplies.

That period is over.

Asset maintenance and Defense Weapons Maintenance continue to have a long time to fill orders. You should A. order a lot at once, and b. look for contracts to fill these. Sometimes the contracts aren't the best for a corporation because the quality and therefore the price of the supply are high and this cuts into your profitability. But if you get most all your supply from the market at the quality/price level you want then getting 1-2 other products that are harder to fill will help keep your costs in check while also keeping your business open. Many enterprises will be happy to provide contracts. Feel free to message Totally McGoods.

Defensive weapons maintenance cost was reduced a bit in the last upgrade.
At the same time, production numbers increased a bit.

This will happen again in the next upgrade.
The aim is to reduce the maintenance cost of the defensive army.

The same applies to defensive weapons.

It might have some influence on the shortages in these products.
Not sure about the numbers.
