What you want to do is make a function that applies the rotation for you like so:
if spot == nil then return end
local NPC = script.Parent
NPC.HumanoidRootPart.CFrame = CFrame.new(regionPos.X, regionPos.Y, regionPos.Z) * CFrame.Angles(spot.rotation)
end
then call it in your if statement like this (assuming spot is a valid instance)
moveToSpot(spot)
end
