Hello, I have been trying to make a custom "Winecellar" on a farm map i made. I followed the tutorials as best I could but I have hit a error wall that i can't find any info on. I'm somewhat new to this so i'm sorry if this has already been answered (I couldn't find an answer here after searching). I made a map that replaces the foraging farm, all i did was extract the xnb, mod it with the Tiled program. Added a new area, the "Winecellar". I added a door and made a warp to the inside at "3 15 Winecellar". I packed all the files back up with the xnbcli program. I made I smapi mod following the instructions on the moddingwiki, This is what my visual Studio looks like, I also have the manifest.json there as well. using System; using Microsoft.Xna.Framework; using StardewModdingAPI; using StardewModdingAPI.Events; using StardewModdingAPI.Utilities; using StardewValley; namespace Winecellarproject { public class Modentry : Mod { public override void Entry(IModHelper helper) { // the game clears locations when loading the save, so do it after the save loads helper.Events.GameLoop.SaveLoaded += this.OnSaveLoaded; } private void OnSaveLoaded(object sender, SaveLoadedEventArgs args) { // create a map asset key for an 'assets/map.tbin' file in your mod folder string mapAssetKey = this.Helper.Content.GetActualAssetKey("Winecellar.tbin", ContentSource.ModFolder); // add the new location GameLocation location = new GameLocation(mapAssetKey, "Winecellar") { IsOutdoors = false, IsFarm = false }; Game1.locations.Add(location); } } } After I build the mod is gives no errors in the error list. Here is my log from the debugger in smapi when I try to run the game: https://log.smapi.io/LurzHXvu I know there is problems, But I can't where the obvious mistake is. I do have the new complied .xnb in my mod folder. thanks for taking a look, Moltar
