A completely server-side implementation of the replay mod, this mod allows you to record multiple players that are online on a server at a time, as well as any given chunk area. This will produce replay files which can then be used with the replay mod for rendering.

The server doesn't crash or anything but idk, thought it might be worth looking into.
