Modern Jobs - Folia Support v1.0.8

New Features
- Level-based XP & Earnings scaling — xp.level-bonus-per-level and earnings.level-bonus-per-level in config.yml give players a growing multiplier as they level up
- New PAPI placeholders — %ojobs_booster_xp_<jobid>% and %ojobs_booster_earnings_<jobid>%, plus %booster_xp%/%booster_earnings% in job item lore
- Custom items in job-menu — job-menu.custom-items in gui.yml now works with job-specific placeholders (%level%, %prestige%, etc.)
- Unified custom items engine — centralised into GuiHelper; adds [message], [player], [console], [close] action prefixes and close-on-click everywhere
- Fully translatable earnings list — action verbs (Mine/Craft/Smelt/…) and the header now come from lang files; all 4 built-in files updated with DE/FR/ES translations

Bug Fixes
- gui.yml YAML fix — click-sound and prev-page-slot were on the same line, breaking the prev-page slot
- %ojobs_job% placeholder now returns the lang-configured "no job" string instead of hardcoded "None"

New Features: - Full perk system (20+ perks across all jobs) + 3 new Perk GUIs
- BossBar XP notifications with earnings placeholders - Earnings multiplier on boosters (separate from XP multiplier) - Job-change cooldown to prevent join/leave spam
- Inline leaderboard inside the main menu
Bug Fixes
- The gui.yml malformed YAML (click-sound + prev-page-slot on same line)
- Night Vision flicker fix for permanent passive effects
- Prestige XP bonus stacking fix
- BossBar cleanup on player disconnect

Data Integrity & Save Fixes
- Fixed YamlStorage saving player files non-atomically — saves now write to a .tmp file first then atomically replace the real file, preventing corrupt YAML on server crash or power loss
- Fixed ConfigManager re-parsing config.yml from disk unnecessarily during language file loading — it now reuses the already-loaded config object
- Fixed MySQLStorage missing DEFAULT '' on the player_name column in the auto-migration ALTER TABLE statement, which caused migration failures on strict SQL servers
---
XP Exploits & Farming
- Fixed a farming exploit where breaking a single bamboo, sugar cane, or cactus block directly on the ground (without another block of the same type below it) would grant XP as if it were a full grown plant
- Fixed a smelting exploit where extracting a large batch of items from a furnace in one event (after leaving items to accumulate) would grant XP proportional to the entire stack. XP scaling is now capped at a configurable maximum (default: 8 items per extract, set via settings.smelting-max-xp-items in
config.yml)
- Fixed shift-click crafting granting XP for only 1 item crafted when the actual crafted amount was much higher
GUI Fixes
- Fixed JobDetailGui opening the Rewards GUI always at prestige 0 regardless of the player's actual prestige level
- Fixed JobsMainGui re-opening the main menu even when leaveJob() failed (e.g. data not loaded), which caused a blank/broken menu state
- Fixed RewardsGui using fragile Java reflection to cancel inventory click events — replaced with a direct instanceof check, matching every other GUI in the plugin
- Fixed all GUI open methods using Bukkit.getScheduler() in the AdminGui reload action on Folia-based servers
Memory Leaks
- Fixed placedBlocks set in BlockListener growing forever — blocks destroyed by explosions or fire are now properly removed from the set
- Fixed trackedPassiveEffects and stoneSenseCooldowns in PerkListener not being cleaned up when a player disconnects, causing a permanent memory leak per logout
- Fixed getOfflinePlayer() calls in LeaderboardGui triggering blocking disk I/O on the main thread for players not cached locally — replaced with createPlayerProfile(UUID, name)
Perk Fixes
- Fixed the Scaffold perk reading and modifying the player's held item from an async/region thread — the item type is now captured on the main thread and the inventory update is scheduled back to the player's thread
- Fixed the Netherite Upgrade perk not cancelling the smithing table event after a successful upgrade, allowing the item to also be consumed by the vanilla recipe handler
Command Fixes
- Fixed /jobs giveexp and /jobs setlevel not validating that the target player had actually joined the specified job before applying changes
- Fixed tab-completion for /jobs stats inserting an empty string "" into the suggestions list when the sender was the console
Code Quality
- Fixed PlaceholderAPI availability check being evaluated at class-load time (before plugins finished enabling) — it is now checked lazily at the point of use
- Fixed MongoDBStorage leaderboard queries crashing entirely if any single stored UUID was malformed — bad entries are now skipped individually with a warning
- Fixed PrestigeManager.canPrestige() calling Optional.get() without an isPresent() guard, risking a NoSuchElementException
- Fixed PrestigeManager.canPrestige() not guarding against maxLevel <= 0, which would allow infinite prestige on jobs with no level cap configured

• Fixed MySQL and SQLite player saves so removed or reset jobs are properly deleted from storage instead of lingering in the database.
• Fixed MySQL and SQLite loading for disabled perks, so toggled perks now persist correctly after reconnects and restarts.
• Fixed passive perk updates so they no longer depend on player movement. Permanent effects now refresh reliably in the background.
• Fixed the Miner night vision passive refresh to prevent the flicker/dark flash effect.
• Improved Hunter tracking and Mob Sense refresh handling for more consistent perk behavior.
• Reworked Vein Miner and Treefeller to break blocks in batches instead of all at once, reducing lag spikes and improving threaded/Folia safety.
• Fixed leaderboard cache refresh so data updates immediately on startup and stale cached entries are cleared before rebuilding.
• Fixed player data loading to keep the correct player name during startup/join instead of falling back to Unknown in some cases.
• Fixed reward parsing for job reward sections that only grant perks.
• Improved action listener handling so only the player's actual loaded jobs are processed, which also avoids issues with disabled or missing jobs.
• Added Spigot API build support cleanup in the Maven setup.
