Version 3.16.6, still happening, using Gemini.
Today cancelling mid-task caused not the whole task but a fair chunk to disappear, including the last user output, and to be replaced with:

This happened a few times in different tasks.

In one task, it happened twice, meaning after resuming and writing new outputs, cancelling erased all the outputs again.

In one instance, clicking Resume Task allowed to continue the task where it stopped, although the related messages did not reappear.

I had this happen to me! seems there is no fallback that if an entry gets corrupted that it can rollback to the last usable state. Does that sound about right?
