You load a schematic, open the material list, and it tells you that you are short 4000 stone
bricks. You are not. They are in the backpack on your hotbar, inside another backpack, where
Litematica cannot see them.
Forgematica Improvements makes the material list count what your backpacks are holding, so the
numbers on screen are the materials you actually have.
Client-side only. Backpack contents live on the server, and this asks for them with
Sophisticated Backpacks' own request packet — the same one the mod's tooltip uses. Nothing has
to be installed on the server, and you can still join servers that do not have it.
