So, i did send crash report (you may check it by current time), and after re-launch of WM i did receive such message after opening of file:
So i lost all progress inside save file. But due to that, that i did have such error on 4030 also, - i did develope habbit to do not just saving, bug a lot of copyies of one file - so you may be not sad about me, EHHEHEHE
Just to clarify - if the autosave file gets corrupted somehow, it should never effect your actual project file on disk. The only exception would be if the crash occured DURING a save action to your project file. Is this the case, or was it something else?
Todays one - did damage only autosave file
but i may pray - half year before while working on project i did lost it fully because WM damaged main file while crash
