Phantom block and missing resources in 1.21

Phantom block, missing item drop and persistent breaking texture when tool is dropped while breaking a block (Java 1.21)

Description

When breaking a block and dropping the tool mid-break, the block can visually remain as a phantom block for several seconds.

In some cases, the block’s item drop is permanently lost. Additionally, the block-breaking texture (crack overlay) can persist and appear on newly placed blocks in the same position.

This issue occurs in singleplayer and is not fixed by F3+T, indicating it is not a simple client-side visual glitch.

⚠ This is NOT a duplication bug. This issue causes permanent item loss.

Steps to Reproduce

Create a new singleplayer world (Java Edition 1.21)

Make sure no mods or resource packs are installed

Take a pickaxe

Start breaking a cobblestone block

While breaking the block, drop the pickaxe (press Q)

Allow the block to finish breaking

Observed Result

A phantom block remains in place for several seconds

If the pickaxe is not picked up, the item drop never appears and is permanently lost

If the pickaxe is picked up, the phantom block disappears immediately and the item drops

After the phantom block disappears, placing a new block in the same position can cause the block-breaking texture (crack overlay) to remain visible on the newly placed block

Reloading resources with F3 + T does NOT fix the phantom block or the breaking texture

Expected Result

The block should disappear immediately after being broken

The correct item drop should always appear

No phantom blocks should remain

Block-breaking textures should reset correctly

F3 + T should clear any purely visual issues
