Storage Center

Storage Centers can stock currently unnecessary resources. Players can set a minimal and maximal amount of storage space for each resource, but it can only hold up to 100 units per resource type.

If a storage center is destroyed, no matter the set difficulty, the entire stock will be lost. The mechanics isn't explained in the game, but can be observed in numerous ways, like by watching the graphs which will display a massive drop.

Logistics
Storing/hoarding resources in a Storage Center is the next-to-last task, priority-wise, and workers will fill them after completing more important tasks. Setting a minimum quantity to have in stock will create higher-priority tasks, but those will remain lower than most common tasks.
