Particles System Issue

I have buildings overlapping in the particles system. I thought i matched the Verts numbers with the emissions value to correct it, but it doesn’t seem to be the problem.
Below is my blend.file:

It does look like hair can be spawned at the same vertex, more than once. I switched it to Emitter and removed the newtonian forces and it seems to work. Just keep your emission count, below your vertex count.

I found the problem though. it was the ‘random order’ box had a default, checked; so i unchecked it. it solved it. weird.!

thank you for your time and effort to help. now i know your method in this, too.
