What if you could add an admin option that would allow you to turn back the clock on a server.
It's not going to be easy to explain this.
Lets say that there are 3 people on a server all doing specific things, one is building, the other is flying around and another guy is driving a jeep.
AND the entire time all of it is being recorded by an action recorder. (Not a video making recorder, a recorder that records what happens in game)
You announce to the 3 users that you are going to put yourself and them back in time to the beginning when the server started.
They agree (Of course)
So you press the turn back time button, the effect is represented by a white flash.
You and the users are virtually unaffected by what happened.
Then, a copy of you (A bot) spawns and begins to perform the exact actions you did when the server had started.
Then the other three users (Bots) spawn in the order to the time they joined the server (Whether they had joined the server 5 minutes later or more or less)
and begin to repeat the actions the users had performed in the past.
If my description of this suggestion is not clear enough, please play this flash game to get the concept.
