Pack Version:
Nomifactory 1.2.2.1

Description:
Basic Fusion Crafting Injector quest's description says "you should plan to make more than eight. If you really want to plan ahead, make thirty-four of these.", but I only need 11 Basic Fusion Crafting Injectors to reach Chaotic Fusion Injectors (I put screenshots to explain how)

Expected Behavior:
description should be "If you really want to plan ahead, make 11 of these."

Screenshots:
Questbook says you'll need 34 Basic Fusion Crafting Injectors

But this works so I only need 11 of them
(I crafted 2 Wyvern Fusion Injectors so I replaced some Basic tier ones)

While you can make as few as 11 basic injectors and replace the injectors in a single setup one-by-one as you upgrade them, doing so is tedious. The quest is telling you the minimum number of injectors you would have to make so that you don't have to repeatedly disassemble and reassemble your fusion crafting setups.

It is by no means wasteful to make more than 11 injectors because you will eventually be making many 10-fusion-injector setups for endgame progression. Using only one setup would be a substantial bottleneck in your crafting speed.
