The Invisible Soda Keg and bizarre force-field-projecting tarp are easy fixes. They'll ship with the next patch.
I missed the Phantom bug from earlier. Looks like it currently doesn't detect it if Brill doesn't actually move. While this is an edge case, it would be good to get this working, so I could probably put the event on the Phantom itself.
EDIT: Yeah, that was easy. It'll ship with the next patch!
