Here is the whole server log until it crashed crash-2018-09-21_14.42.15-server.txt Heres the crash report Yeh thats it all I had a backup from a day ago and it worked , however i have made alot of progress and my friends have as well and it would be bad to reset back , and i would know what to do in the future. I tried moving the world file to the backup to see if the world could transfer , as i didnt make any changes to the server , apart from play on it.However it didn't work and i dont know where to look for help as google didnt help. Please help asap and any info would be appreciated if you want to know what mods its probably in the log somewhere thanks
