Brave New World Bug Fix

After reading about everyone's atttempts at troubleshooting the Chairman crash in Brave New World, I noticed a common thread. The only people who managed to fix the bug, did so by sending Felix back to the ship. Now, I didn't have Felix in my party, but I did have two companions (Max and Ellie). Upon dismissing Max, the glitch was fixed.

Thus, I believe the bug is caused by attempting to take two companions into the final room.
