There is a different set of mounts that have an issue with sync - and that is a separate problem that should also be fixed by Jared's code. So people with those mounts - like EQMod - if you leave them in the sync mode where it doesn't actually sync, but instead it adds a point to the model - does Jared's code work for centering? It should work no matter how sync behaves because it doesn't use sync in the first place - I think.
