That's strange. I've taken a look through the reported errors and don't see anything that looks like what you describe. If you could send me the save file I'll take a look and see what's going on.
Thanks, I think I found the problem. Looks like a weird corner case around saving right as a unit died. I'll have a fix in 2.0.3, as a temporary workaround try changing (or disabling) the autosave interval from Settings in the main menu.
