Simply specifying instanced strands works fine here, I cannot reproduce the crash. Most of the modifiers work too. I have noticed, however, that adding Ox Mesh from Strands modifier does cause a crash. I will investigate that.
Instanced strands are a way of reducing memory footprint of Ornatrix by making it reuse the same hair over and over again at many locations. It usually means that you need to use polar interpolation. In most cases, you do not need to use instanced strands however.
