The setBlockSkin() method always returns false despite the block containing a playerhead and the ID being accurate.

How to replicate:

Placed a regular player_head on the ground. Tried to convert to a particular hdb head using an ID, but failed.

        Block b = e.getClickedBlock();
        if (b.getType() == Material.PLAYER_HEAD) {
			HeadDatabaseAPI hdbApi = new HeadDatabaseAPI();
			Bukkit.getLogger().info(Boolean.toString(hdbApi.isHead("29431")));
			Bukkit.getLogger().info(Boolean.toString(hdbApi.setBlockSkin(b, "29431")));
