TypeError: e is undefined

Hello all,

I'm trying to programmatically create a cylinder using the following:

    var cylinder = BABYLON.MeshBuilder.CreateCylinder("wormhole", {diameter: 1, tessellation: 24}, this.resourceStore["GameScene"]);
    cylinder.position = BABYLON.Vector3(-0.56, 1.27, 1.235);

and it is throwing a TypeError: e is undefined with the following trace:

o</i.prototype.copyFrom()
babylon-2.4.min.js:1
t</i.prototype.computeWorldMatrix()
babylon-2.4.min.js:6
o</i.prototype._evaluateActiveMeshes()

GameManager.js:191
bound ()
self-hosted
c</o.prototype._renderLoop()
babylon-2.4.min.js:4

Any ideas? Everything works fine (i.e. scene loads, textures show, materials work, controls work). I have noticed lately that my textures seem to disappear at a particular camera but the geometry is still there. Not sure if its related.
