The rules haven't changed.
Yeah, it seems crazy that a President can win an election with fewer votes than his opponent. In programming, we call an "edge case." An edge case doesn't always require a rewrite, or throwing out the system. Edge cases are anomalies that sometimes need to be accounted for, but more often we just live with them because it's too expensive to fix them all. Can you imagine having to recount all votes nationwide, in case of a close election? It's much more manageable to recount just votes in close districts that could make an electoral difference. In other words, the Electoral College serves a practical purpose, and doing away with it would cause significant expense.
I guarantee that if Hillary had won with fewer popular votes, the press would be talking only about the amazing electoral win, not the "divided" country.
