Placing objects in MapEditor appends to the end of the list. This causes chronological order (oldest on top -> newest on bottom) during a mapping session.
Saving in MapEditor stores that list in a JSON file, under data[]. But the order is scrambled/destroyed.
You can make a pseudo prefab, by selecting A, B, and C in the list with Shift + LMB during chronological order. But when A, B, and
C are spread out in random locations across 3000 objects, the pseudo prefab requires manually selecting each object in the world.
