Ok thats settled it then (I take your word for it that 1.6 fixed this despite no mention in patch notes). I meant to post it here at the time I took it, which would have been 12 days before patch 1.6, but I forgot... so this exploit was available for at least 12 whole days before something was done about it?
But that's another matter, there are more than enough threads already about lack of bug fixes.
Some "server firsts" on ECNiM might have to be looked at more closely And with the trainingstatue-companionenabling-heroicmoment-legacymoves exploit in operations? Ooft.
