Server wont work after rollback

I was playing with a friend, we screwup the deerclops fight and rolledback 1 day. After the rollback my server is unstable, some times it will show up as a server and be avaiable for connection and other time (most of the times) won't show up not even through the steam friends list. 

I created another server to check if the problem was the map or the cliente, and the new server works 100% of the times.
