First off BabylonJS is awesome!
I am having a problem with CSG currently. This error I get only seems to happen on Chrome on Windows. Edge on Windows and all Mac works fine.
I have an app that is creating CSG on the fly. This is for a foam case building app that I am working on. For a gun shape that has two circles for finger notches as seen in the 2d image below. You can also see in the image below the points of the polygon I am rendering. We've added two circles to the render as well. When I run this as a `CSG subtract` in BabylonJS on Chrome on Windows for certain shapes, with an example below. I get the following error:
Uncaught TypeError: Cannot read property 'normal' of null

This error is a little bit beyond my understanding of Babylon. I don't think that I have any complex lines where the lines are over lapping one another and I also don't know how to catch this error. Would be great to be able to catch the error if we can't fix it.
Again thanks for the great library.
