Just tested it, and this TerraFarm worked just fine on Loma. So it's going to have to be a conflict on your end. Make sure you only have one version of TerraFarm in your mod folder. There is also a garbage mod, I think by Redneck Modding, that will prevent TerraFarm from working.
Well, I tried with just the map and this Terrafarm mod in the modfolder. The map loads up, but when I buy like a shovel the game crashes.. Unfortunately.
