I recreated the Shipping Depot in thieves Landing from RDR1 however i could not get rid of the old structures, you can do it temporarily with Map Editor (by temporary i mean until you close the game) and even making a map file where i deleted the wall pieces didnt work so the original building sort of goes through the warehouse sorry i couldnt fix
Put the Ymap file in your Stream folder
