I was just about to give up at 70th generation, when the walkers suddenly evolved from 1 to 4 steps in 5 generations.

Currently at generation 120 with 7 steps, looks like it is "evolving" in bursts, with long periods of nothing.

Well it is stuck at 9 steps at gen 400+.

I wonder if the author got any further. I would say this is close to the limit.
