[Question] Trouble with Seed spawn on Biomes

[Ronivan]

So again hello everyone. Its been a while since I'm working on Dupes Cuisine Mod, which is available on Steam here. I'm updating this mod, and introducing a new crop and recipes. However I'm facing a trouble while trying to force the seeds of these news crops in the vanilla biome. The code I'm using to archive this is as follows:

using System;
using System.Collections.Generic;
using System.Linq;
using Harmony;
using ProcGen;

namespace Dupes_Cuisine
{
    public class Plant_Subworld_Patch
    {

        public List<string> tags { get; private set; }

        [HarmonyPatch(typeof(SettingsCache), "LoadFiles")]
        public static class KakawaSeed_Patch
        {

            internal static void Postfix()
            {
                foreach (WeightedBiome weightedBiome in SettingsCache.subworlds["subworlds/forest/ForestStart"].biomes)
                {

                    weightedBiome.tags.Add("KakawaSeed");
                }
                Debug.Log(string.Join(",", SettingsCache.mobs.MobLookupTable.Keys.ToArray<string>()));
            }
        }
    }
}

If I place any vanilla game seeds ids on this, it works perfectly. The seeds will spawn on the selected biome, alright. However, if I use any of my mod's seeds ids, it don't work. I'm no expert in C#, and I'm still learning a lot on how to properly code for ONI. With this said, I just want tips on how to archive this with my seeds ids. Anyone could point me the right direction on how to solve this?
