The large commodities building has been in the works for close to 2.5 months now and seems to approach the release time as everything seems to be getting done. 

The latest beta test has been successful with the updated collisions and tip areas on the mod that allow you to dump bulk material out. 

Please note that you CAN NOT dump mineral in this as the game is not set up for it from the looks of it. 

Expect this to release in the next week or two.
