Hey. It might be a simple mistake because I just started learning bukkit, but I spent like 2 hours trying to fix that. I tried reinstalling JDK and updating Java, tried redownloading plugins. EVERYTHING worked perfectly yesterday, but I did something and it started crashing. Essentials do load. If I don't try to get players balance or do anything with essentials in my code it runs perfectly. Error: https://pastebin.com/mWnTAx1J Code: https://pastebin.com/GjgKmMys Thanks.
