[Kruize1]

REQUIREMENTS

1. PWI - "perworldinventory-kt-2.3.2"
2. Paper Server version 1.16.1
3. Need a separate world created with a separate inventory. (example: "world_red_blue")
4. End Dragon will likely need to be defeated for this to work

STEPS TO REPRODUCE

1. Have a player set spawn in another world with a separate inventory than the ones shared in "world", "world_nether", and "world_the_end" (example: "world_red_blue")
2. Let player travel back into "world"
3. Let player travel to "world_the_end"
4. Have player stash all items from inventory into a chest
5. Let player exit "world_the_end" via End Portal Exit (End Fountain)
6. Note > Player is sent back to their spawn point in alternate world (ex. spawn point in "world_red_blue")
7. Allow player to go back to "world"
8. Note > Player will have their whole inventory they stashed in Step #4

RESULT

• It seems as if exiting via the End Portal Exit (End Fountain) doesn't update and save the player's inventory.
• When they return back, their inventory is restored

EXPECTED RESULT

• Exiting via End Portal Exit (End Fountain) should save the player's inventory
