Quoting Jorb
Decay: "Constructions (kilns, ovens, smelters, and houses [when decay is implemented for them] etc.) should now be built on paved stone tiles. You can still build them on open ground, but they suffer 4x the normal rate of decay if you do. Also, objects decay 2.5 times as fast in Mordor as they do at the RoB, or equivalent."
