Reading the Vasudan letter again, it sounds as if the "recordings of a battle" that half-myriad-guubers made could be the actual, finished campaign (for example, in a password-protected zip-file).
"Take a look back at the first post in the thread."
Hmm, the first thread was "Can anyone hear me".
I only notice this:
"And if you're an engineer, you're going to want proof. Not that any engineers have Ash's chance in Shiva of stumbling across the obscure, obsolete corner of the holonet where I have to hide this, but if I'm going to be a fool, I might as well be a fool who makes sense."
We have probably found the "obscure, obsolete corner of the holonet". The word "Shiva" is weird in that sentence, but that could very well be a substitute for the word "hell", just to add flavor. But who would Ash be? Possibly one of the beta testers?
Of course, one could just explain that the campaign had been at this locationm yet the GTI pulled the file before we could reach it. But what kind of happy end to our quest would that be

...
So... Any idea who Ash could be?

Alternatively, if it he really means the first post in
this thread. then that would be MikeRoz's comment "You've got to be kidding me." Or, of course the title of this thread could be meant - we are "always one step behind"...
