A hacker destroyed all buildings

[BebeyGurl]

Me and my friend was playing on the smp earlier, My pc turned off because it didnt have battery and i said to my friend i need to get a charger, and then my mom called for dinner. I said i needed to go to eat! I hhad a smp before and just like this without the dinner happend and while my pc was dead, a hacker joined and destroyd everything. so yeah i knew the risks but i took them, so i ate dinner and when i came back and my pc has charged, my friend called me and said a hacker had burnt down the smp. i joined and all of our building was destoryed! it wasnt burnt down it was like he wiped out planks from the world!" chest and stuff like that was there!he had just wiped out planks from the world! now i have a destroyed smp and dont know what to do. if Minehut can set our server back to an earlier version before yesterday? like 3 days from now that would be great.

If you have any backups use those

Your server is also automatically backed up every hour, but I'm going to assume you've been on the server for longer than that after the grief. In the future try using the most recent save
