I also took z0=b^b ~ 1.69 as initial point; the curves originating from z0=1 were even more messed up. This is the picture base b=1.44 z0=1+0î - I've no explanation so far for the messed curves. Well, here is the same, but now taken with the "regular tetration" which uses the fixpoint-shift and works with power series without constant term.     At least, using the base b=1.3 the differences to the polynomial method are at order of 1e-7, so this picture might not be too distorted.
