[Retail] nPower not updated need help with error code.

Hello,
NeavUI has not been updated sence 08/27/18 some people have tried to do quick fixes but not everything is updated. One of the addons I use from it is called nPower and it works but keeps thowing me a error everytime a load screen comes up.

Here is the link to the GitHub for the addon to see the whole addon. nPower

the error code I am getting from BugGrabber is:
Code:
411x nPower\core.lua:209: attempt to perform arithmetic on local 'start' (a nil value)
nPower\core.lua:209: in function <nPower\core.lua:207>
nPower\core.lua:388: in function <nPower\core.lua:373>

Locals:
self = 1
start = nil
duration = nil
runeReady = nil
(*temporary) = <function> defined =[C]:-1
(*temporary) = 342594.828000
(*temporary) = 342594.828000
(*temporary) = nil
(*temporary) = "attempt to perform arithmetic on local 'start' (a nil value)"
It seems to only happen on my Deathknight. the chunk of code that is being referenced is:
Lua Code:
  1. local function CalcRuneCooldown(self)
  2.     local start, duration, runeReady = GetRuneCooldown(self)
  3.     local time = floor(GetTime() - start)
  4.     local cooldown = ceil(duration - time)
  5.  
  6.     if (runeReady or UnitIsDeadOrGhost("player")) then
  7.         return "#"
  8.     elseif (not UnitIsDeadOrGhost("player") and cooldown) then
  9.         return cooldown
  10.     end
  11. end

and this function only seems to show up in this bit of code at the end of the .lua:
Lua Code:
  1. if (f.Rune) then
  2.     local updateTimer = 0
  3.     f:SetScript("OnUpdate", function(self, elapsed)
  4.         updateTimer = updateTimer + elapsed
  5.  
  6.         if (updateTimer > 0.1) then
  7.             for i = 1, 6 do
  8.                 if (UnitHasVehicleUI("player")) then
  9.                     if (f.Rune[i]:IsShown()) then
  10.                         f.Rune[i]:Hide()
  11.                     end
  12.                 else
  13.                     if (not f.Rune[i]:IsShown()) then
  14.                         f.Rune[i]:Show()
  15.                     end
  16.                 end
  17.  
  18.                 f.Rune[i]:SetText(CalcRuneCooldown(i))
  19.                 f.Rune[i]:SetTextColor(0.0, 0.6, 0.8)
  20.             end
  21.  
  22.             updateTimer = 0
  23.         end
  24.     end)
  25. end

Hopefully one of you awesome programmers have an idea why this keep throwing an error.

Thanks in advance for any help solving this issue.

In my rune code I check that start has been given a value (Blizzard does also in their UpdateRunes function which probably means GetRuneCooldown can return nil for start no matter what the online docs say) so a change to something like:

Lua Code:
  1. local function CalcRuneCooldown(self)
  2.     local cooldown
  3.     local start, duration, runeReady = GetRuneCooldown(self)
  4.     if start then
  5.         local time = floor(GetTime() - start)
  6.         cooldown = ceil(duration - time)
  7.     end    
  8.     if (runeReady or UnitIsDeadOrGhost("player")) then
  9.         return "#"
  10.     elseif (not UnitIsDeadOrGhost("player") and cooldown) then
  11.         return cooldown
  12.     end

Here's what i'm using and built around nPower code.

Lua Code:
  1. local A, C, L = select(2, ...):unpack()
  2. local RuneBar = CreateFrame("Frame")
  3. local DataBars = A["DataBars"]
  4. local Panels = A["Panels"]
  5.  
  6. -- Lib Globals
  7. local select = select
  8. local unpack = unpack
  9.  
  10. -- WoW Globals
  11. local GetRuneCooldown = GetRuneCooldown
  12. local GetTime = GetTime
  13. local UnitClass = UnitClass
  14. local GetSpecialization = GetSpecialization
  15.  
  16. -- Locals
  17. local Class = select(2, UnitClass("player"))
  18.  
  19. -- Color Tabels
  20. local Mult = 2.5
  21. local BloodColor = { 1 * Mult, 0, 0 }
  22. local FrostColor = { 0, 0.35 * Mult, 1 * Mult }
  23. local UnholyColor = { 0.25 * Mult, 0.55 * Mult, 0.10 * Mult }
  24.  
  25. function RuneBar:OnUpdate(Elapsed)
  26.     local Duration = self.Duration + Elapsed
  27.     self.Duration = Duration
  28.     self:SetValue(Duration)
  29. end
  30.  
  31. function RuneBar:Update()
  32.     for i = 1, 6 do
  33.         local Start, Duration, RuneIsReady = GetRuneCooldown(i)

  35.             self.RunesBars[i].Duration = GetTime() - Start
  36.             self.RunesBars[i]:SetMinMaxValues(0, Duration)
  37.             self.RunesBars[i]:SetScript("OnUpdate", self.OnUpdate)
  38.         else
  39.             self.RunesBars[i]:SetMinMaxValues(0, 1)
  40.             self.RunesBars[i]:SetValue(1)

Thank You @Fizzlemizz it works perfectly, it so nice not hearing the "fatality" every time the screen loads.

"fatality" is what that Gnome voice says? I've wondered for years what that was, but was too lazy to figure it out.
