[+]Finally: Move Tag system from PersistentDataContainers to Database (MySQL / SQLite). It's now fully asynchronous, bungeecord/velocity-compatible and should work a lot better than before. Give it a try! With tags, you can save ANY kind of data for any player. Why is this useful, you ask? Well, for example, you can make an own, completely custom currency system with that. A point system. A relationship system between NPCs. Or villages. Custom nickname for a player. Anything.
[!] Fixed bug where objective rewards are not skipped-over during playerdata loading and only during plugin loading
