World objects and creatures with no item, placed with the Unreal summon command.
Single player or host only, with UE4SS's CheatManagerEnablerMod and ConsoleCommandsMod.
Nothing summoned survives a reload: it is gone when you load the save again, along with anything
stored inside it. What you get from it (salvage loot, trades) is kept.
Every class here was tested in game; the few that do not simply appear are marked
(moves away, invisible, no spawn).
