Block duplication IE + Cyclic

[rubin0]

Issue / Bug

Cyclic sack of holding can "store" blocks of IE multiblock structures without destroying the structure. These stored blocks can be placed and broken with a pickaxe, duplicating them.

Expected Behavior

Sack of holding should not contains IE block entities.

Possible Solution

Blacklist IE multiblock entities?

Steps to Reproduce (for bugs)

Blocks are not duplicated with the Sack of Holding.
The original blocks are not in their original old position,
the multiblock is displayed, but it does not work anymore.

When the Multiblock structure is destroyed, the blocks that were transported with the Sack of Holding are missing.

This should be fixed for 3.0.8
