Expected Behavior

Pickup whole bed or block pickup

Actual Behavior

Pickus up half of bed leaving both halfs that both drop the bed item, duplicating the bed. This would likely be the case for other "multiblocks" from that mod too

Steps to Reproduce

1. Place bed (Mine was "Black Modern Bed")
2. Pickup bed (I picked up lower half)
3. Place again - even if you place the new half in the correct place, they will still be disconnected
