When reporting an issue, please try to reproduce the issue with just Dominos and Dominos_Config running. Dominos reuses a good chunk of the stock UI, and other popular addons, like Move Anything, like to take control of those parts, too.

The PossesBar not working correctly in classic era.

4x Dominos\bars\possessBar.lua:136: Usage: GetPossessInfo(index)
[string "=[C]"]: in function GetPossessInfo' [string "@Dominos\bars\possessBar.lua"]:136: in function Update'
[string "@Dominos\bars\possessBar.lua"]:199: in function <Dominos\bars\possessBar.lua:197>
[string "@Dominos\core\helpers.lua"]:176: in function <Dominos\core\helpers.lua:175>

Locals:
(*temporary) = 0

If you change line 136 to local texture-- = (GetPossessInfo(button:GetID())) then it will fail the if statement in line 139 with
1x Dominos\bars\possessBar.lua:139: attempt to call global 'UnitControllingVehicle' (a nil value). Seems that
UnitControllingVehicle and CanExitVehicle does not exists in classic era api.

Addon Version
10.0.2-classic

World of Warcraft Version
Classic Era

10.0.3 should resolve this one.

yes, ty :-)
