I just had a very annoying incident. I had two scenes open in IC2012(64)PU2. Scene A was linked into scene B. I've been working on the geometry of A for two days, sometimes in A, sometimes in B. I saved A (but not every hour or so. Then things suddenly went haywire and IC started producing error messages galore. Since I had just saved A a few minutes earlier, I simply quit IC without saving A or B. Then I restarted IC an re-opened A - just to find that all my recent work was lost Indeed, the timestamp on the files was more than 24h old! Was that my fault, i.e. is that behavior expected? Or di something in IC go wrong?

It is difficult to tell from your message what may have gone wrong. Are you able to reproduce the issue?

No, and I hope I won't. So clearly, when you save a scene, it should be written to disk, even if the scene is linked into another scene that is open at a same time, right?
I just want to make sure, I'm not doing anything wrong.
