I'm currently using this version of the Arrow on Orbiter 2016 and I'm absolutely loving it, but I noticed that while the Arrow consumes Oxygen during a mission it doesn't seem to save Oxygen status in the scenario file when you exit. So when you re-start Orbiter you're always at 100% Oxygen, no matter what level you were when you quit the mission. In other words it works fine if you do everything in a single session, but if you save, quit and restart, you immediately end up on 100% O2.
Not a huge issue, but its a bit of a shame since the author went to all the trouble to add O2 consumption / replenishment functionality so I just thought it was worth a report. If it cant be patched, is there any way of editing the O2 levels so I can make a note of it before exiting and then edit it back to where it should be when I re-start?
