Around Facility level 5-7 the Warehouse scaling really hits.. Material upgrades cost 3.2Million up but warehouse is at 490k and costs huge amounts of materials to upgrade. And can't offline or idle because the existing warehouse will fill. Really becomes awkward to play :(
Could you make the auto-buy not buy anything if it cannot buy everything, or at least cannot buy a reasonable proportion? It is unfortunate to have a major creation finish and then spend several trillion divinity on the first few prereqs for the next one, but not get them all and get stuck making fish for a few years.
Awesome job on fixing the prerequisites. One more request for that though: add a "keep" quantity for each resource so that if you have a monument building, you can create something with prereqs without the materials for the monument being spent.
Bug - the automatic creation of items you need gets confused if an item itself has needs. For example if you have stone and air and you try to create plant, the game will correctly make soil and water. But if you have no stone, the game will try to make soil, work out that it needs to make stone to do this, but then get stuck and make stone forever instead of returning to make soil and then plant.
More seriously there is still a weird "feature" where at high levels the more profitable ventures are cheaper. It's much cheaper to go from 300 to 400 oil derricks than it is for 300 to 400 lemonade stands.
