None of those plugins initiate map restart that I recall.
We had this kind of same thing, but when someone joins the server, and you spawn in, the server immediately restarts the map after 5-15 secs. I think it's a bug to do with the server waiting for more players before scoring can happen. But might be something else.
Only happens when server is empty and the first person joins.
Maybe you have people joining your server at that time and then they disconnect when it restarts the map?
