The mod was very useful ... It will be a pity if it is left without support.
I rummaged a bit, but I did not know much in the scripts, found where the conflict was.

MyAPIGateway.PrefabManager.SpawnPrefab(
null,
"SuitBackpack",
player.GetPosition(),
new Vector3(1f,0f, 0f),
new Vector3(0f, 1f, 0f),
new Vector3(0f, 0f, 0f),
new Vector3(0f, 0f, 0f),
null,

==>> SpawningOptions.EnableSave, <<==

player.IdentityId,
true
);
}

But maybe I'm wrong ....
