I'm struggling with creating new playerdata (the server's one in /world/playerdata/[uuid].dat). I write a plugin which should make fake players to be banks (but in fact regular fake players) and hold money (I use Vault API). I thought that this one would do its job: Code: PlayerProfile profile = Bukkit.createProfile(UUID.randomUUID(), bankName); I use Paper 1.17.1 as my dependency. However no playerdata is created and if I try to check if this player exists in game, it says that it can't find it. I also use CMI plugin and I would like the solution that is compatible with this (I mean that this new player will be instantly recognized by it - that it exists). Is there any method to create a [uuid].dat file? Or should I write my custom method, and if so, how should I start with that? I would be grateful for any hints on that, since I've been looking for a solution for a quite lot of time and that's one of the last things I need in my plugin to be usable. Thank you for your help.
