    Alright so it's been a while seen I've tried modding Stardew Valley, over a year I think? But with it coming out to the switch tomorrow I've gotten back into the game, and an old project I was working on.

    Basically I was trying to add a new NPC called Dakota. I managed to figure it out, but I can't remember how anymore since it was a while ago, and because of the game updating the old mod I was working on doesn't work anymore.

    So I'm redoing it from memory, but honestly I have no idea if what I'm doing is right anymore. I'm getting an error with SMAPI, but my NPC is showing up in the game and in the villager list:

    Stardew Valley 1.2.33 - running SMAPI 1.15.4 with 4 mods 10_4_2017 2_16_00 AM.png Stardew Valley 1.2.33 - running SMAPI 1.15.4 with 4 mods 10_4_2017 2_16_34 AM.png

    She just isn't following any schedule for some reason, even though she has a schedule XBB file. If anyone could give me some pointers as to what I'm doing wrong I'd really appreciate it.

    (Also, I don't know C#, only Java, so my code's probably a mess.)

    Here's my code so far:

    using System;
    using Microsoft.Xna.Framework;
    using StardewModdingAPI;
    using StardewModdingAPI.Events;
    using StardewValley;
    using Microsoft.Xna.Framework.Graphics;
    using System.Collections.Generic;

    namespace CharaExpansionMod
    public class ModEntry : Mod
    public override void Entry(IModHelper helper)
    GameEvents.UpdateTick += GameEvents_UpdateTick;​

    private void GameEvents_UpdateTick(object sender, EventArgs e)
    if (Game1.currentLocation != null)
    if (Game1.getCharacterFromName("Dakota") == null)
    foreach (var i in Game1.locations)
    if ( == "SeedShop")
    var test = new NPC(new AnimatedSprite(Game1.content.Load<Texture2D>("Characters\\Dakota"), 0, Game1.tileSize / 4, Game1.tileSize * 2 / 4), new Vector2((float)(8 * Game1.tileSize), (float)(7 * Game1.tileSize)), "SeedShop", 2, "Dakota", false, (Dictionary<int, int[]>)null, Game1.content.Load<Texture2D>("Portraits\\Dakota"));

    if (!Game1.NPCGiftTastes.ContainsKey("Dakota"))
    Game1.NPCGiftTastes.Add("Dakota", "Wow I can't believe you got this for me! Thanks!$h/64 336/Hey this is pretty neat, thanks!$h/-28 420 257 281 107 305 247/What? You're giving me THIS? Thanks...$s/80 348 346 303 -74/Is this supposed to be a joke?/390 388 330 571 568 569/Oh... Thanks?$u// ");​

    And the error from SMAPI:

    [01:47:03 ERROR SMAPI] A mod failed handling the GameEvents.UpdateTick event:
