Bug in PointValues

[KnutAM]

Shouldn't dMdξ be updated here as well with the new quadrature point location...

Ferrite.jl/src/PointEval/point_values.jl

Lines 59 to 66 in fd0b999

	function reinit!(pv::PointValues, x::AbstractVector{<:Vec{D}}, ξ::Vec{D}) where {D}
	qp = 1 # PointValues only have a single qp
	# TODO: Does M need to be updated too?
	for i in 1:getnbasefunctions(pv.cv.ip)
	pv.cv.dNdξ[i, qp], pv.cv.N[i, qp] = shape_gradient_and_value(pv.cv.ip, ξ, i)
	end
	reinit!(pv.cv, x)
	return nothing
