Changelog — v2.3

• Bugfix: Fixed a false-positive "already opened" bug on singleplayer worlds, where two different saves with the same world name (e.g. both left at the default "New World") could incorrectly share their "opened vaults" list.
• The fix went through two iterations, ending on the robust one: the mod now stamps a small random-UUID marker file (trialvaultesp-world-id.txt) directly into each singleplayer world's save folder on first use, and uses that as the world's identity instead of its cosmetic name or its save folder name. This survives folder renames, and correctly gives a genuinely new/recreated world a fresh identity instead of risking it inheriting a deleted world's stale data (which a folder-name-only fix could still have hit if a name got reused).
• ⚠️ Previously-recorded "opened" entries won't carry over (saved under the old, less reliable keys) — harmless on singleplayer since the accurate live server-data check takes over immediately; on multiplayer you may need to re-mark a vault or two if you'd hit the original collision there.
