not really a bug. but I keep getting disconnected (I'm blaming it on my internet, as I loose all connection, not just STO). But having an Autosave, set up, would be very nice for those times which you loose connection, forget to hit 'save' etc. so one doesn't have to start over from sratch every time.
Actually, there has been one in place... at least for me. There have been numerous times where I've lost connection but it saved an autosave version. Maybe it's no longer working or maybe it's a bug on your end but there has been one in place at one point.
