There’s a bug in 3.8.1 that can cause RCLogbook to crash when working with helicopters that log fuel. The crash can happen on either the flight complete or the flight edit pages of the UI. The bug has been isolated and squashed and a fix is on its way in release 3.8.2. While we were in the code, we tweaked a few other things to improve stability and robustness.
To work-around the crash, your best option is to turn off fuel logging while flying and record fuel usage the old fashioned way. Once 3.8.2 is out, you should be able to go back into the flight editor and update the fuel consumed.
The update was submitted this evening, should be out sometime next week depending on how busy Apple’s app approval gnomes are these days.
Apologies, as always, for the inconvenience…
