A temporary fix (or update) for the heads ... Put it in your vault, close the vault - open your vault, and it should update...
It should work as long as you take precautions The API still operates on string names, which looks up the UUID, then retrieves the texture ID at that time. Once you see that the texture in the items icon itself, its saved to it... But you cant ever place that head in the vault, or else it will be reset. Placing in vault, then in inventory I know initializes the texture, so try that.
use vault, but youll need to be using the skin you want it to stay as when you take it out of the vault.
Not something I'm going to do. Vault stores data in a reliable fashion that doesn't involve NBT. Now, if Spigot added the profile properties to the serialization that would work - but the problem is not everyone maybe wants that behavior.
i just noticed a change by spigot upstream that seems like it will resolve this and save the skin ID as part of the items serialization. We will update soon
It would come when we update the servers next (any update). We need to do some testing on the current changes as they are numerous, and there is no accurate time that this will occur.
well there was no guarantee next update would contain that update, but I did happen to do it last night.
I've noticed a bug with player heads stacking....For example, let's say I kill ikapela in the PvP arenas and get her head, then kill her again and the heads would stack. Then, the next day I would kill her and get her head but the head wouldn't stack with the ones from yesterday. I tried using vault tricks like opening it and closing it while transferring the heads back and forth. Idk whether this argument was already about this (because I'm not good with big works ) but this "bug" has been making my eye twitch every time I PvP.
I had three AverageWalrus heads that didn't stack. I had no idea about the vault trick until I read this thread. I just did it and now the three heads stack. This may be a stupid question, but are you closing your vault and reopening it? That is what I did.
