Replacing heads still drop as an item

Can confirm.

Can confirm for Redstone block too.

EDIT:
Acting like a player. If it breaks stone, you get cobblestone etc.
Tested for multiple other blocks.

Confirmed for:

• 1.8 Also you get the error message (with block=air): "The block couldn't be placed" (that's MC-50166)

• 1.8.4 Could relate to the fact that Minecraft displays *nodrop:false* in F3 screen

Still an issue in 15w35b snapshot even if replace or keep arguments are used to fill skull block with the same skull.

Confirmed for 15w51b.

Please link to this comment in the description

The following is based on a decompiled version of Minecraft 1.9 using MCP 9.24 beta.

For flower pots the reason for this is that they do not implement the interface net.minecraft.inventory.IInventory and therefor the method net.minecraft.inventory.IInventory.clear() does not exist and is not called to clear the contained items.

For skulls the problem is that currently the method net.minecraft.block.BlockSkull.breakBlock(World, BlockPos, IBlockState) drops the skull (should be rather called "onBlockRemoved"). Instead the method net.minecraft.block.BlockSkull.dropBlockAsItemWithChance(World, BlockPos, IBlockState, float, int) should do this. The problem with this is that the former method removes the tile entity first. The order of this should be probably changed.

Is this still an issue in the most recent versions (currently that is 1.10.2, or 16w43a) of Minecraft? If so, please update the affected versions and help us keeping this ticket updated from time to time. If you are the owner/reporter of this ticket, you can modify the affected version(s) yourself.

Yes, it is. 🙂

Skull still drop when using /fill and /setblock
Confirmed for 1.12-pre5

Flower pots are no longer affected in the latest snapshots because they are not using a block entity anymore.

Leaving it in because the latest release (1.12.2) is still affected.

Also appears to affect jukeboxes now (the record is dropped).

All Heads (except for the player head) are no longer affected in the latest snapshots because they are not using a block entity anymore.
Leaving it in because the latest release (1.12.2) is still affected.

or maybie not

This appears to be fixed for skulls / player heads in the latest version. The report MC-138067 tracks this for jukeboxes so we don't have to remove the skull information from this report.
