Summary:
teleporting inconsistent when entities overlap

Impact:

The hesitating greatly impacts the visible impact of a feature in an upcoming piece of content

Repro Steps:

1. Press the "Play" button
2. Choose the first option on the dialogue that opened up
3. Press Play!
4. Look at the contents of the window on the right. specifically when you press "up" to move your char forward

Observed Results:

Note that all of the entities move upwards in sync except the bottom one which hesitates almost a full second. this is consistent when the game is running

This occurs specifically when the client is under any amount of load. if the commands are not running, this (likely graphical issue) does not reproduce. This can be verified by doing the following commands when a game is not in progress:

/function bug_repro_setup

/function bug_repro

Expected Results:

the entities should move at the same time

Regression Build:

likely a long standing issue

Notes

Read the function to see the code but I teleport all the entities before summoning the entity that replaces the bottom one in the same tick.
