Bug Fixes
Fixed GUI Items Appearing in Player Inventories & Graves After Death
Affected: Servers using use_bottom_inventory: true with grave plugins such as AxGraves.

A regression introduced in v2.5 could cause GUI filler items to appear in player inventories after closing a GUI or dying. In some cases, grave plugins would also save GUI items instead of the player's real items.

Fixed Snapshot Corruption

• Removed the syncSnapshot() system entirely.
  
  
• Snapshots are now captured only once when the GUI opens.
  
  
• Added targeted slot updates through updateSnapshotSlot() to keep snapshots accurate without overwriting them with GUI items.
  
  
• Prevents GUI filler items from being saved into inventory snapshots.
  

Fixed Missing Items in Graves

• SmartMenus now patches the death drop list before grave plugins process it.
  
  
• GUI-marked items are automatically removed from event.getDrops().
  
  
• Real items stored in the snapshot are re-inserted into the drop list.
  
  
• Ensures grave plugins receive the player's actual inventory contents.
  

Improved Inventory Restoration Safety

• Added PDC validation during inventory restoration.
  
  
• Any GUI-marked item accidentally present in a snapshot will be ignored and restored as empty.
  
  
• Prevents future edge cases from reintroducing GUI items into player inventories.
  

Improved Death Handling

• All physical slots used by bottom_items are now cleared before inventory restoration occurs.
  
  
• Guarantees GUI items are fully removed before real items are restored.
  
  
• Improves compatibility with AxGraves and similar inventory management plugins.
  

⚙️ Internal Improvements

• Replaced full inventory snapshot re-syncing with efficient per-slot updates.
  
  
• Reduced unnecessary inventory cloning operations.
  
  
• Improved reliability of Bottom Inventory GUIs during inventory modifications and player death events.
  

Build Changes

• Version bumped from 2.5-SNAPSHOT → 2.6-SNAPSHOT
