I hate griefers... They love ruining people's hard work. Next time, be careful to let only people you know onto your servers. Also, if you know who was responsible for the mess, you could get them back. You can learn two valuable lessons from this: make backups and don't give everyone your server IP.
man that sucks, but it was predictibal if you dont have any backup or protection, even if you trust the people on the server, there are allways things like hackers, harddisk failure and stuff like that, there is never an excuse to not make backups, make backups often AND have somekind of protection system.
And you didn't have a backup of what you make?
I do a daily backup of my world which is a single player map. You have a server and don't have any update tools? You deserve this for being ignorant and thinking that no one would do that.
And just think....in those 180 hours you wasted, you could have gone outside, gotten laid, gotten shitfaced or high and had the time of your life. Life is too short to waste on games, friend :wink.gif:
