Nuka-World bugs

PC only

 * The alien animatronics in the Gauntlet and the Galactic Zone will sometimes cause an instant crash to desktop when shooting.
 * Attempting to put any of the Nuka-World exclusive automatron parts on a robot, such as the Nuka-Cherry launcher causes a game freeze. Reloading the exit save causes the automatron to disappear.

PS4 only

 * Bringing another add-on companion to Nuka-World (such as Ada or Old Longfellow then talking to Gage and making him your companion will cause whatever companion you sent away and all their carried items to be lost forever. They will never appear at the location you send them to and cannot be found on the map.
 * Trying to get Gage as a companion while you already have one will occasionally cause him to bug out, causing your current companion to return where you sent them, but Gage will remain where you spoke to him, repeating his recruitment lines when spoken to and becoming undismissable. He will still fast travel with you, but will always remain still, even when attacked.
