acronym

just wondering, but I logged onto the server at about 1 pm pacific time on 9/4/13, and found that someone had made holes in my wall, and took all of my machinery and chests, and the kicker is that it everything was at least 3 blocks in the towns radius, so they had to have came through 3 blocks of a town then get through the walls to get my stuff, and I was just wondering if it was possible to roll back the server or if I had to restart all over again, towns name is SpiHyrEru

just wondering, but for the town plugin that you have, is there any rules or anything of that sort for having nations on your server?
