Erm... Well, I've never recorded anything either, so I probably shouldn't say anything, but I will anyway... :P
don't know why the kill count in the first mortem is that ridiculous.. maybe I've pasted that part from another wrong mortem? Geez.
I'm confused about why you would be pasting parts from different mortems in the first place. :| I'm not accusing you of anything, but if you don't want people to think you're cheating, then I suggest you stop doing that and just paste the one mortem from the game you just played without any changes whatsoever.
I've lost the mortem file indeed.
This also confuses me. The game saves the mortems automatically and you should have all of them together in your mortem folder. (Personally, I have every single mortem from every game I've ever played for the last four years, all the way back to version 0.9.9.1) All you have to do is do a search for all files containing the phrase "Iron Skull." It should be a short list. :)
