Edit: After checking through my thousands of e-mails again, I found the one that talked about the change to 1.04. At the time, Wildbill and I were working in tandem on the project and regularly sharing new files back-and-forth. I had given him a file that contained updated monster edits, but it unfortunately got overlooked and didn't make it into the final patch. I didn't realise this until sometime later, and that's when we created the 1.04 patch
I hope this clears things up.
