You have to be a Grimoire regular to get that joke.
I am working on the manual today and tomorrow all day. I have it in a rudimentary form and am trying to fill it out with the essentials. The game is so dense that writing about Grimoire's mechanics makes you realize you have a lot more to write about Grimoire's play mechanics.
There is also a new update coming tomorrow that will be the first that isn't trying to fix an assert. Grimoire "asserts" are in reality logging events that require a full stop because some data was encountered that just isn't right at that moment in the game. Those seem to have vanished after some small redesigns of the code in a few places, hopefully they won't be coming back.
