VScript freezing game when leaving map

[beepster4096]

class Class {
    vector1 = null;
    vector2 = null;

    static instances = [];

    constructor() {
        this.vector1 = Vector(0, 0, 0);
        this.vector2 = Vector(0, 0, 0);
    }
}

Class.instances.push(Class());
Class.instances.push(Class());

Running this script and leaving the map will freeze the game.
