Our server dragon.nuclearfallout.net seams to be having an issue where it will spontaneously add 15 min to the timelimit over time. We normally have it set to 30 but if we don't moniter it, the map limit gets over an hour. This is not good for player moral
I have not heard of this. I recommend you go in our IRC support channel have a tech look at your server. A plugins could be cuasing this. But it does sould like people are extending the map by vote.
I found the problem. By default the new steam servers do not exec server.cfg every map change. So when a map got extended, it would keep the extended time frame cvar.
You need to add the following line to your server.cfg file
mapchangecfgfile server.cfg
Then every map change your server.cfg file will be executed.
