Random Unit Appearances Issue

I am having a problem when trying to give unit types random appearances based on unit variables. For most things, it works fine, but when the unit is walking and its path is blocked, it simply uses the first frame in the still animation, regardless of the setup of the animation. Is there a way to solve this issue?

This is the animation code that I am using:

--
-- Dwarven Scout
--

local ScoutStill = {
 "if-var v.GraphicsVariation.Value == 1 variation_1",
 "if-var v.GraphicsVariation.Value == 2 variation_2",
 "if-var v.GraphicsVariation.Value == 3 variation_3",
 "label variation_1", "frame 0", "goto end",
 "label variation_2", "frame 60", "goto end",
 "label variation_3", "frame 120", "goto end",
 "label end", "wait 4", "random-goto 99 no-rotate", "random-rotate 1", "label no-rotate", "wait 1",}
local ScoutDeath = {"unbreakable begin", "frame 45", "wait 3", "frame 50", "wait 3", "frame 55", "wait 100",
    "frame 55", "unbreakable end", "wait 1",}

  Still = ScoutStill,
