Maintenance

Every building, unless otherwise specified, will require resources to be expended to maintain the building at its current level on a monthly basis. The maintenance costs will be a small percentage of the same resources required to upgrade the building to its current level and will vary based on the amount of usage of the building (production) over the course of the month. The maintenance cost for a building can be paid at any time, and can be paid for multiple months at one time, however if the full maintenance cost for a building has not been paid by the end of the month then the building will drop down one level.

When a building is upgraded to a new level or when it is first constructed, the maintenance cost for the first month will be part of the construction costs, so maintenance payments will begin in the second month after a building is constructed or upgraded. If a building is upgraded, any maintenance costs that were paid in advance will be applied towards the maintenance costs going forward after the upgrade. Please keep in mind, however, that the maintenance costs will increase each time a building is upgraded.

It is planned that the maintenance cost for a building will be proportional to how productive it was in the previous month, so that means a building that had 100k Production on average for a month will have a higher maintenance cost the following month than the same building with 10k Production on average. There will be a minimum maintenance cost for all buildings even if they have not actively produced anything over the previous month.
