Christoph Oelckers 7fa3081581 - fixed some remaining issues with the interpolator.
Thanks to the lazy counter it used in its stat display I never noticed that the serializer was incomplete and that UnlinkFromMap did not call its super method.
After changing the counter to be actively counting on each call, all the other issues became immediately apparent.
