There are two bugs in the manual.
The first is that there is no "Slow Voxel Dematerializer" page, but the "Slow Voxel Materializer" is present twice. It is obviously a problem because it is the only way of obtaining the recipe, except for looking inside the code
The second bug is minor: there is no mission 21. It seems like that it is not missing and the numbering is just shifted, but I will report anyway.
Hey, nice work with this update! There are many issues with the game, but it is very fun! Good work!
