Hi, I'm not sure what is causing your refueling conditions to re-trigger, they are working fine in my game. I added some additional checks to try and prevent re-triggering but they aren't tested.
Senior Officer in System should be fixed now.
Unable to refuel or resupply should no longer cancel all orders.
If you are still having issues please send the quasar4x.sqlite file in which I can end the turn and observe the problem. If it's difficult to predict when the issue will happen, you can enable backups after every turn in the settings window.
Version 135 is up with the code changes, but I have not verified any of the fixes.
