I don't blame shadrock for failing the version Stefan had...heres some things Stefan said about the 5 month old version which Shadrock saw:
(after I asked him to describe it in a PM, here was his reply)
" Well: a generated overworld, no houses at all,
a few (good) ganis "
That is nothing like Murasamune, except a few good ganis..but not even thats true, cause we have many great ganis

...heres another thing, the thing I got the 5 month number from:
" Someone has sent me a 5-months old
version of your pw, didn't look different than
the thing i have tested 5 months ago

"
So with that, I know Shadrock still hasn't seen Murasamune...which is good, because I didn't want him to get it, not yet anyway.
