I don't even know what "plant" means. I just spent some time Googling this and there isn't a single thread with that icon displayed or explained. Not a single legend of icons mentions it.

Can build and fill the plant but the end product the Pepsi pallets is not produced and displayed...no matter on which map...what is the reason?

Kann die Anlage zwar bauen und befüllen allerdings wird das Endprodukt die Pepsi Paletten nicht produziert und angezeigt...egal auf welcher Map...woran liegt das ?
