Building Upgrades Suggestion
Detailed Description
Currently, if you upgrade your corporate headquarters, the price to perform the upgrade is the same no matter which level you are currently at. Therefore, you can go all in for the highest level from level 1 and it would cost the same as if you went from the level right below it to the highest level. I would like to propose that it be adjusted so that for example if you want to upgrade from level 8 to 9, it costs less than total than if you upgrade straight from 7 to 9. Or possibly make the amounts cumulative. So for example, if you want to upgrade straight from 6 to 8, the cost is the price of upgrading from 6-7 plus the cost from 7-8.
