Factory Maintanence - State Corps

When I go to build a new Corp, the list of Material Requirements for most corps shows 20 Fact Maint units required per month. However, after my corps have been running a few game months, they appear to require 75 to 120 Fact Maint units per game month. This is a huge expense. Anyone know what is going on here?

As your corps grow they will produce more product and probably at a higher quality. This naturally requires more supplies and supplies of a quality higher than the initial 100Q they start with. This is definitely a result of having >100Q supplies and upgrading your production process quality.

Increases in salary and welfare will also increase the corps production, so increasing the supply costs.

The up-side is, you are making more product of a higher cost to the market and so making more profit (generally speaking).

good luck, post again if this still doesnt make sense. CC
