Souped Up Strangeling Multiplayer Farming (Soup Kitchens)
This exploit allows you to harvest as many Souped Up Strangelings (soups) as you'd like by hopping back and forth between two multiplayer rooms.
This requires at least two accounts that have cloud save, and will not gain soups.
This exploit works because you cannot enter the same treasure grove soup room twice in a row, but if you enter one, and then another, you can re-enter the first and so on.
Steps to accomplish:

  1. Two people/accounts clear a treausre grove to the room before a soup room.
  2. Those people exit the grove and very importantly, SAVE TO CLOUD.
  3. Those two people host and post two multiplayer session details (the soup kitchen).
  4. The two hosts head out, enter the soup rooms, and AFK while others enter.
  5. Other players join the rooms back and forth collecting soups.

After an hour, the soup rooms will need to be reset. To reset them:
  1. The two people/accounts quit to title.
  2. Select Cross Save Inspection from the title screen.
  3. Restore from the crossave.
  4. Re-host the multiplayer session and re-enter the soup room.

It's worth noting that having more hosts allows more players to move between rooms, and faster.
