Yes, We've had similar thoughts... unfortunately, unless one has a reliable method of persisting values to the server then one buggy script, or addon will bring you're 24/7 mission to an abrupt conclusion.
At which point all volitile mission variables will cease to exist...
I've scanned the wiki new scripting commands and nothing there seems to look able to save mission info.
Unless someone's going to build a 'hook' of the 'loadfile' command like keg's then how were you planning to accomplish persistence?
Or am I missing something?
