Yes, clearly there is an issue with the Schrodinger equation. I think it is very obvious that basic quantum mechanics (with the Shcrodinger equation) does not apply to the entire universe. It would be better to talk in terms of quantum field theory, and maybe the scattering matrix there is unitary, but already know that is in contradiction with general relativity. Basic quantum mechanics is only a very rudimentary model. Basic quantum mechanics is only a local theory, and there is zero reason to apply it at the scale of the universe. Not to mention, if there is such a thing as a universal wavefunction, it is probably extremely complicated and contains a lot of information. Looking at a very small slice of it (a planet) may indeed look very complicated. While the entire system might be unitary, that doesnt mean every component is unitary.
