From Farshid Lashkari : "I reported earlier about a problem with a custom emitter I was using. I spent some more time debugging and it turns out there was a bug in the ParticleSystem::update_bounds function. When the bound is being reset, both the min and max are being set to the same postion without the radius being subtracted/added to it. When there is only one particle alive in the system this causes it to be culled by small feature culling. I've modifed the function so that when the bound is reset, the radius is subtracted/added to the position. This fixes my problem."
