.... The game sort of 'resets', but nothing changes.

I concur. Only tried it offline though, with 'em bots.

It works. Try /realistic 1 to set it on.

It doesn't ;)

It works on the dedicated server, where did you try it?

Indeed, I tried on my dedicated server and it works fine.

Well it doesn't work on a non-dedicated server then..
