Steps to reproduce:

1. First step: Created a spell that adds me and other players nearby to a list
2. Second step: concatenate the two lists
3. Third step: reading out the combined list shows the entities in an unexpected or incorrect order

What I expected to happen:
When I used Add to list or Concatenate list I expected it to add entities in the order the lists were in previously
What happened instead:
The entity list positions were randomized or sorted into an alphabetical order of some sort instead of retaining their individual list orders.

I have attached an example image of the readout from a similar code below where [1] is the combined list. Note that the caster is in the middle of that list despite being added to a list of nearby players. this should have added the player to the start or the end of the list, not the middle.

Code being expermented with below;

It hasn't been properly documented (sorry about that, it'll happen Soon™), but Entity "List" is a bit of a misnomer.
Lists don't actually stay in order when you merge them; it is only guaranteed that the same list of Entities keeps the same ordering for that list of Entities. When making a new list, all bets are off.

Pinned for now until the behavior gets properly documented
