Part going through the floor

I’m not sure if this is an issue with my game, but for some odd reason my enemy is fazing through the floor.

Testing.rbxl (48.6 KB)

Full Code:

task.wait(2)
local Points = workspace.Points
local Enemy = workspace.Enemy
local Node = 1
local Speed = 5
local OverallDeltaTime = 0
local CornerStatus = 0
local Turning = false
local Repeat = false

	local l2 = Lerp(p1, p2, t)

	return quad
end

	return Vector3.new(Pos.X, 0, Pos.Z)
end

As you can see, the highlight outline is in the floor.
