AFAIK, the $$, Conscripts and WSU arre"global" and get shared in all regions.
The only real restrictions are the previously state ones, particularly WSU for single Artillery units and some ships.
I'll look at the concept of Artillery being built in the West, vs. in a particular state... eg. MO, TX and AR would build artillery currently resticted to eithr MO or AR.
Note, however, that currently, the only states/cities west of the Mississippi producing WSU at start are in Union control,so we're back to either waiting to industrialize, adding WSU to the setup, or further expanding the raiserule area.
hmmm, or removing the WSU location requirement from 6lb and Horse Artillery.....
...or some combination
I'd need to see a save where you ordered an Infantry-type and didn't get it, but be sure you had a city that met the requirement for Military Control and Loyalty before and after executing the turn.....
