Nothing's wrong with IntegerPart, Plot doesn't necessarily sample the
point you expect by default. You can increase the number of points and
subdivisions to get what I assume is your expected Plot:
Plot[{prefstate[[IntegerPart[x]]]}, {x, 1, nSize}, PlotPoints -> 67,
MaxRecursion -> 6, AxesOrigin -> {0, 0}, TicksStyle -> Directive[18],
PlotStyle -> {Black}]
