Sinking craft double chest protection

[ethankdoan]

Describe the bug
It happens about half the time when a ship sinks and when the ship hits the seafloor at y ~ 30 the craft continues to exist and the anvil noise associated with a "cannot translate craft" repeatably sounds. No message appears to the player but the sound continues until disconnect. The craft continues to exist with no player attached (using /craftreport) and cannot be broken (with piloted ship protection on). Usually no error in console occurs.

To Reproduce
Steps to reproduce the behavior:

1. Install Movecraft and place a ship ~1000 blocks
2. Sink the ship /scuttle or tnt works
3. Wait for it to sink
4. Observe repeated cannot translate anvil noise.

Expected behavior
Proper sinking, craft collapses properly and stops existing.

update: This bug seems to happen to ships with barrels on them

This likely is the anti double-chest merging protection kicking in and preventing the craft from moving in a way which could create a double chest (or a double barrel).

In a similar vein, forbidden blocks should also not stop movement of sinking crafts.
