This has personally been an ongoing issue for me for a while. For nearly 3 years now I've developed and maintained a heads plugin that allows the selling of heads (and a lot more but this bit is relevant to the thread). However, it has not been unusual for me to receive a complaint saying all NBT data in the head is lost after placing it and breaking it again, which I have to explain every time is not a problem on my end and is in fact the work of Minecraft itself: you place a diamond block with a custom name and lore, all of that is lost; the same goes for skulls, clearly. I've even made an option that prevents players from placing these heads, however, for those who want to show off those heads, it's not the most suitable option. In the past, I do recall something on Bukkit mentioning the practice of saving NBT/metadata before, and that someone made a utility for it. However, my searching skills look like they've gone down the drain or I simply can't find it anymore (this was about 3 years ago as well before I even released my plugin and decided I wasn't going to try and fix that issue, especially since I'd gone and made the same mistake almost everyone does and didn't learn Java before coding plugins, so I barely knew a thing it did). But I'm also wondering if someone has actually re-created that utility but in the form of a plugin of which I can recommend to users of my plugin complaining of the issue? I would be happy making my own if there's none available, although I'm trying to avoid this because I already work on two other major plugins (one which I plan to be extremely destructive with) and have another in developing, as well as a crap ton of schoolwork and revision to do, despite I'm mostly trying to achieve this in school hours. I won't ask for anyone to make it either; if it's an interesting concept to you and you want to try it yourself, go ahead, but I'm not paying anyone anything (especially since I don't have PayPal either). TL;DR: Is there a plugin out there - or even just a utility - that can save ItemStack NBT/metadata after that item is placed on the ground as a block, so that players using my plugin don't continuously report the same issue with me giving the same answer (Minecraft issue, not fixing)?
