Try this fix.

And I also found a bug, please download this behavior again.
The key is the configuration of (A,n,B,m). I use try & error.
I usually fix the attracting force to 1 (A=1, n=0, B=0, range = 0),
and rejecting force changed by distance (B=500, m=1, A=0, range = 100), push out when too closed.
Thanks for sharing this capx.
