Error importing vertices data in incremental loading

Hi guys,

I'm trying the incremental loading functionality in order to see if it could be useful for complex scene cases.
I used the MakeIncremental tool to create the incremental files. When I try to load the .incremental.babylon scene file I always get an error when in import vertices data step.
I created a playground for this problem:

I thinks could also be useful to get some images of ma debug steps (in attachment). As you can see the problem seems to be in the call to updateExtend.

The function is called without any input and the call to

data = this.getVerticesData(BABYLON.VertexBuffer.PositionKind);

returns null.

The lib version is the 3.2.0-beta.4.
Thanks,

Matteo
