UPDATE: Went for a more direct and absolute approach, and found a bug with Raul that deserved fixing.

If you've ever spent any time in the Lucky 38 Presidential Suite while your Companions are waiting there, you may notice that they have a habit of picking up EVERYTHING and using it. This doesn't just stop at things that are out on a table or something, they will actually take things out of lockers, wardrobes, and other containers... AND THEN EAT THEM. Sigh....

This fix puts a stop to that. First, it completely disables the "Eating" and "Sleeping" routines in every Companion's AI package when in the Lucky 38 Presidential Suite. They will still wander, engage in conversation, and sit on furniture, but they won't eat your stuff or sleep in your bed.

Secondly, the fix sets most containers in the Lucky 38 Presidential Suite as "Ignore Sandbox" and "No AI Acquire", meaning that companions not only won't try to get stuff out of them, for all intents and purposes they don't even know they exist.

The second part applies to EVERY container you can purchase using the upgrade terminal, and every container located in the Master bedroom (where your bed is). It also does the same for the fridge located in the kitchen area (the one you don't have to purchase).

Additionally, this fix also sets your bed as off-limits, and the single bottle of "Jake Juice" found in the rec room area. No real reason, just seemed flavor-appropriate.

And finally, this fix addresses a slight bug with Raul being sent to the Lucky 38. Observant players may have noticed that Raul does not wander the Presidential Suite like other companions. This is because his Lucky 38 "sandbox" package was not set as a "sandbox" package, meaning he does nothing but sit there like a lump. The fix changes that, ensuring Raul will wander the Lucky 38 just like anyone else... but without eating all your food.
