WebGL: INVALID_OPERATION: bindBuffer: attempt to bind a deleted buffer

[iSoundy000]

Engine.prototype.unbindInstanceAttributes = function () {
    var boundBuffer;
    for (var i = 0, ul = this._currentInstanceLocations.length; i < ul; i++) {
        var instancesBuffer = this._currentInstanceBuffers[i];
        if (boundBuffer != instancesBuffer && instancesBuffer.references) {
            boundBuffer = instancesBuffer;
            this.bindArrayBuffer(instancesBuffer);
        }
        var offsetLocation = this._currentInstanceLocations[i];
        this._caps.instancedArrays.vertexAttribDivisorANGLE(offsetLocation, 0);
    }
    this._currentInstanceBuffers.length = 0;
    this._currentInstanceLocations.length = 0;
};

The webglBuffer is already deleted,but when call function unbindInstanceAttributes , I add one condition  "instancesBuffer.references", is OK? @Deltakosh @RaananW

you "can't" ?  we have a great kickstarter to learn how to work with bjs in TS: http://doc.babylonjs.com/generals/how_to_start

Regarding the issue, I'll do the fix, no worry. Thanks for finding it
