Thanks, itichi
I think "Going crazy" it is bugged. In fact these achievements aren't difficult but missable, so I doubt we two (and some more) haven't found it.
By the way, finally I found my last hidden one, so 41/43 too.
We don't want to spoil anything, but we also want to state, that the trophy "Going crazy" isn't bugged and never was in any released version.
