It seems there can be rare conditions where an interpolation is 'lost' and later garbage collected. If that happens after the owning map is gone, all pointers in the interpolation object will be invalid and Destroy would crash while trying to unlink it. So anything that explicitly deletes an interpolation now has to manually unlink it from the map first so that OnDestroy can be kept clean of map references.
