XSG-1707

I've been doing some VOR approaches at EFRO (RL instrument rated pilot) and have found there to be a problem with the VOR alignment. Most VORs are kept "aligned" to magnetic north so to fly outbound on radial 360 in nil wind a magnetic course of 360 is flown. From my reading of the EFRO charts there is no VOR misalignment so I can be considered to be correctly Mag North aligned. However the published radials do not work correctly. After investigation it seems to VOR North value is the problem. Resetting it to 0 corrects the approach tracks. After further investigation I believe the VOR North value moves the 360 Radial relative to Magnetic North. As the XPlane Mag Var database has, I believe, been recently updated then all VOR North values would need to be adjusted as the VORS were referenced to a moving datum. Perhaps at one point it was intended to ref the VORs to True North a that would be a fixed datum, but that doesn't appear to be the case now. Can one of the developers please detail the purpose of the VOR North value and perhaps investigate if it should have been updated when the Mag Var table was updated? Thanks.
