For a while now my Messages has been randomly choosing to send my messages to either the normal, contact number (Jane Doe, 555-555-5555) or to the number with an Argentinian country code tacked on (+54 9 555-555-5555). The messages still get where they're going but it's a problem because my conversations with most contacts are now split between the two "different" numbers and group conversations are heck.
Has this problem ever been seen and addressed before?? I'd be pretty relieved to fix this somehow.
