Hello Celia, this kind of mail please to the MIRA talk mail. That being said: what you saw is something out of the sphere of control of MIRA ... but basically it should not have happened. A file which MIRA worked on just moments ago was suddenly "not there anymore" as reported by the operating system. This seriously cannot be, I suspect a glitch of the OS / hardware. There's one other thing which makes me scratch my head: does your machine really have 256 physical CPU cores? You can try to start a new assembly, but I would monitor this machine very, very closely.
