Life support commodities eaten by HQ with none for production
Oxygen and fuel are bottomed out at $10 each, but glass is $150. I scrap electrolysis and build glass furnaces, because, it makes financial sense. This creates a rather large demand in my HQ for oxygen which is purchased on debt. I build 3 glass furnaces and have enough cash to buy a little oxygen to supply the glass furnace, and bam, its eaten up by the HQ demand, and the glass furnace sits there requesting oxygen. Glass production discouraged. Same thing happens with Chemicals, which need fuel.
I really think the debt mechanic need to be reevaluated. The rules are squeezed at one end to prevent an issue, but its pushing an unintended consequence at the other.
