I load into a creative world, and press [o], it shows my origin correctly
I go through a nether portal, and press [o] and is says 'you cannot have an origin'.
I go back through the nether portal and press [o] again with the same results.
changing origin with an orb of origin does fix, until I go through a portal
i have not tested ender portals yet, but the portals of the "TARDIM" mod also break it.
