Had to completely delete the BIAB folder and reinstall everything to get build 312. We are customers not testers. I have spent countless hours trying to work around bugs and even had to reinstall BIAB 18 at one point. Looking at the number of builds since release and the number of fixes this product was never tested properly. Worked in software development and we called this testing in production. Learned my lesson and will never purchase again until all the builds are released.
