1.3.9+26.1

This is a technical/maintenance release: no new features, focused entirely on fixing a serious data-integrity bug in the World Journal and finishing the in-game command support that had been requested but never actually shipped.

Fixed

• World Journal entries mixing between different worlds (major bug). On this Minecraft version, the way the game reports a singleplayer world's own save folder could resolve to the same generic path for every world instead of that world's actual folder. As a result, every singleplayer world ended up sharing one single journal file instead of getting its own — so a brand-new world could show deaths, trades, advancements or notes that actually happened in a completely different world, and deleting a world and creating a new one with the same name could resurrect the deleted world's entries.
  • Each world's journal is now tied to its own save folder through a small hidden marker file stored inside that folder, completely independent of the folder's name — this can't reoccur, even if you reuse an old world's name.
  • If you had already been affected, opening the singleplayer world list now shows a one-time recovery screen (it keeps appearing until you act on it) offering two choices: delete the old shared file and let every world start with a clean journal, or pick which of your worlds should receive the old file's recovered entries.
• /journal commands now actually exist. These had been asked for previously but never wired into the mod:
  • /journal add <text> — logs a manual entry on the current in-game day, without opening the book screen
  • /journal removeday <day> — shows how many entries exist for that day; running /journal removeday <day> confirm deletes all of them
  • /journal clear — shows a warning about what's about to happen; running /journal clear confirm permanently wipes the current world's entire journal
