Save loading cut foliage

I am trying in every way to save the foliage that I cut, I created a structure that contains the reference and the index of the mesh removed in runtime, I saved it in an array, when loading I added 2 print strings that confirm the type of foliage and its index, I apply the “for each” node to the array and consequently “remove instance” also connecting the Index node between them. Unfortunately it does not work. I do not know where to turn, I found only one tutorial but it did not help me.
