Player.js errors in actor viewer in Atlas

[Stan]

When opening atlas, opening actor viewer, I get this error

<p class="warning">WARNING: JavaScript warning: simulation/components/PlayerManager.js line 76
reference to undefined property this.playerEntities[0]</p>

If I try to change the player I get these errors (I changed it to 6 and then to 1)

<p class="warning">WARNING: GetPlayerByID: no player defined for id '6'
  PlayerManager.prototype.GetPlayerByID@simulation/components/PlayerManager.js:78:14

This error is reproducible since at least Alpha 19

This is also a duplicate of my own ticket #4900

[elexis]

How do you come to that conclusion?

Same line ?

Oh, was looking at #4657, sorry for the noise. Since this one contains information that isn't present over there, might want to ref it at #4900.
