So I recently my server just crashed randomly and everyone timed out. The server came back on, worked fine then when a certain player joined it crashed. I know exactly which player it is when it crashes. I have tried deleting his files from and essentials and the world. It didn't work. If u can help, please. Anybody who is having this issue, please just don't post, I have this issue. If you do have this issue post some more info the issue so it can go to finding a solution.
Can you please post the error you are getting once your server crashes? More information is needed to help you out further.
