yes, I agree with Fusili.
I just double checked this (albeit without crashing Logic but not saving after recording) and the audio file, as it should be, was residing in the audio files folder of my project folder.
Alex, did you save your project at all? Or do you have a different record path? When recording audio Logic will try and make you save first before recording arming an audio track.
File > Project Settings > Recording...
to check whether you have a specific recording path. otherwise it will be in your project folder > Audio Files.
