Ah I see the issue. SetPedArmor() is being used instead of SetPedArmour(). I’ll update this in a future update. However, for now simply go here:
SetPedArmor()
SetPedArmour()
And change SetPedArmor(ped, 100) to SetPedArmour(ped, 100)
SetPedArmor(ped, 100)
SetPedArmour(ped, 100)
That should temporarily fix it.
