I explored the world on my server when suddenly the game crashed. The server started to work slowly seconds before the crash and it felt like it was too much going on at the moment for the program or the computer. On the server log did this came up several times before the crash: 08:51:51] [Server thread/WARN]: Can't keep up! Did the system time change, or is the server overloaded? Running 4366ms behind, skipping 87 tick(s) I have add the crash report as an attachment below. This has happened many times in a row now and everytime i join the server it crashes just minutes after i started it.
