Currently, if a player deconstructs a tent with an another player inside, upon leaving the tent this player will be teleported to the exact spot where they entered it.

Instead, we could track the item position, and whatever entities/blocks that pick it up or end up containing it. This way upon leaving the tent the player would be teleported exactly where the tent is.

Not only it's more logical, but it's also makes for a hilarious mechanic as you can literally carry your friends in your pocket. It'd also unlock more cooperative potential, as the player inside could also throw items and even push entities through the same door. Considering arrows are also entities, you could probably even shoot from withing the tent.

For an easier solution, a compromise could be made, where we only track players holding the item, and if at any point no players hold the item and the tent is not built, we simply record its last known location.
