Now you can remove NFT Saudis from the oil rig and move it to another one.
Also, at one oil field you can change oil rig - choose oil rig on the market or in the inventory (if purchased earlier) and put on the one you want to replace, the removed oil rig is placed in the inventory.
Every Honourable Saud must keep a barrel of black gold in his warehouse!
