Faster compression & Imperial Camp boxes

Well unless I've mistaken, there's no way to ever get the chance to step on those particular boxes though, even by way of going to the secret Barrier Ring chest... so I'm a bit baffled how it could happen. I mean of course those boxes would cause the character to become stuck if the character walked on them, due to the tile's properties, but if there's no way to have it happen without hacking then it's not an issue, right? Jumping over to the Barrier Ring tent has the character on autopilot, back and forth, never getting the chance to touch the boxes. Then when escaping the camp, the event triggers prevent it. Is there another way?
