Better Fishtanks

Thread-Safe Loot Generation: FishClassLootManager now uses ConcurrentHashMap and AtomicBoolean to ensure that the loot tables are generated only once, even if multiple threads try to do it at the same time. It also uses ThreadLocalRandom to avoid issues with the Random class.

Client-Side Loot Generation Removed: BetterFishtanksJEIPlugin no longer calls generateLoot(). Instead, it relies on the server-generated loot tables. This ensures that the loot displayed in JEI is consistent with the loot that players will actually get in the game.

Enchanted books now actually have enchantments when generated by cracking fish eggs in the Aquarists Table.

Fixed an issue that caused the Fishtanks UI to open and close if the Player was too far away. [this might still sometimes occur, but it shouldn't be as often as before]
