It won't get fixed because IW is finished with Ghosts. The next CoD is 6 months away and they want to make as much profit as possible. It will also be an issue in the next CoD because Sledgehammer won't care either and then when TreyArch finally gets their turn they won't do nothing either.
They've been using the same damn engine for 10+ years now and they end up creating more problems rather than solutions.
