Bailed? Ryan McCartan was always scheduled to be in it for a short time due to his commitment to his TV show. Yes, Alice Lee left for the singing competition but the girl playing Heather Duke right now, Kristolyn Lloyd, actually originated the part in Los Angeles. So is Barrett who you're referring to as the lead who "bailed"? Because it was a lot more complicated than that and had nothing to do with the transfer. Beyond the three of them, I'm not even sure who you're referring to as the fourth lead who isn't still with the show, as Jessica Keenan Wynn and Elle McLemore probably have the largest parts outside Veronica, JD, and Heather Chandler and both are still happily with the production.
No transfer is confirmed, that's true, but it's silly to throw around statements like that when they're just not true.
