Use SystemState.state.Instantiate to instantiate prefabs but the parent relationship was broken. The only different was the Transform.scale

add photos…
And if i change the scale to (1, 1, 1), the relationship will be right.

And the spawnersystem code is

using Unity.Entities;
using Unity.Transforms;
using Unity.Burst;
using TinyRTS;
using Unity.Mathematics;
using UnityEngine;
using TinyRTS.Utils;

namespace TinyRTS
{
    [BurstCompile]

    {
        // private static bool init_flag = false;

        {
            //foreach (RefRW<Spawner> spawner in SystemAPI.Query<RefRW<Spawner>>())
            //{
            //    InitProcessSpawner(ref state, spawner);
            //}
        }

        public void OnDestroy(ref SystemState state) { }

        [BurstCompile]
