Market Warehouse

Market warehouses are trading spots scattered around map. Once discovered, they are marked with white dot on radar map like artifacts. Unlike artifacts, their white dot marker is visible also on world map and stay visible forever.

Useful information:
 * Market Warehouses are indestructible.
 * Discovered Resource Deposits claimed by Market Warehouse will not reward you with Credits.
 * Artifacts claimed by Market Warehouse are useless for player, because they are considered as "neutral player" property. You will also be unable to use Strange Towers (teleportation divices) trapped inside Market Warehouses claim. Since Market Warehouses probably weren't meant to prevent players from using Artifacts and considered you cannot remove (destroy) Market Warehouses, this may be fixed in future updates.
