Shortages

What is the best way to fix the shortage issues for corps? My corps are constantly running out of things and I tried changing when and much much they buy but it still doesn't fix it ;(

For most products you can just raise the low water mark on the corp supplies page. For me 15 mo. low and order 10 seems to work.

Other prods are in severe shortage and the only way to get them is either immediate order or contract/direct sell to yourself.

There are severe shortages.

on the corporations page, use the order tab.
you can turn all orders into immediate orders at once and fix all shortages in a single action.

the cost is higher but having corporations not producing anything is more costly.
