@stk2008 If you're using the default 'SUBSPACE' mode, your son might be in an earlier "time frame" than you. Either change to a different mode or make sure you're both synced to the latest subspace time. As for the lag, I had a lag problem before and it turned out to be related to the "max physics delta-time per frame" setting. If you've tweaked that setting, try resetting it to default and see if your lag problem goes away.

I'm running KSP 64 bit in Linux, and the mod seems to work great, except for one thing. The enter key doesn't work in the flight computer, so I can't set a delay or an absolute rotation. I can click buttons and enter text just fine, but the enter key doesn't actually do anything. I suspect it's related to the Linux build issue where keypresses always affect everything. In fact, when entering something like '55m22s', it will go to the map view when I enter the 'm'. Is anyone else using this mod in Linux?

Been using this, and I love the realism it adds. I noticed a bug, though: the air vents subtract oxygen as I land on Kerbin. I read somewhere that they should add CO2 instead of oxygen in non-Kerbin atmospheres, but it appears they remove oxygen and add CO2 in Kerbin's atmosphere also. I'm using the dev4 build. The systems are definitely using resources even while unfocused now, but the scrubber still stops working as soon as I unfocus the ship, so if I stay unfocused from a ship for too long Kerbals will die from the CO2 buildup. I solved this temporarily by making CO2 buildup non-lethal.
