WowAce

WoW version: 10.2.5
addon version: v4.4.6

I get this error every time I ride a vehicle

10x ...ceShadowedUnitFrames/modules/combopoints.lua:27: Usage: local result = GetComboPoints(unit, target)
[string "=[C]"]: in function `GetComboPoints'
[string "@ShadowedUnitFrames/modules/combopoints.lua"]:27: in function `GetPoints'
[string "@ShadowedUnitFrames/modules/basecombopoints.lua"]:180: in function `Update'
[string "@ShadowedUnitFrames/modules/combopoints.lua"]:40: in function `?'
[string "@ShadowedUnitFrames/modules/units.lua"]:36: in function `FullUpdate'
[string "@ShadowedUnitFrames/modules/units.lua"]:1556: in function <ShadowedUnitFrames/modules/units.lua:1520>

Locals:
(*temporary) = "vehicle"

This is still an issue in the latest version.

fix update modules/combopoints 
line 28 => local points = GetComboPoints("vehicle", "target")
