As of right now, there is a strange situation where you absolutely need to randomly find (pre-fabricated) autoclave pouches to be able to sterilize a CBM. You can’t re-use the pouches, and no substitutes are allowed.
From gameplay perspective, this feels like a very bizarre bottleneck, as everything else for bionic installation (tools to dissect with, cleaning reagents, anesthesia, autodocks, autoclaves, etc) can either be crafted, or exists as a guaranteed statistic spawn in certain locations. Moreover, the fact that the bags spawn in 25-units stacks makes them essentially all-or-nothing: once you’ve found one stack, you’ve got enough for nearly all your future CBM-related needs.
From realism perspective, it also does not make much sense that you cannot use a 3L glass jar with a lid (or something similar) to sterilize the CBM in.
Unless autoclave pouches are supposed to act as a hard bottleneck, allow for a reasonable substitute (aforementioned 3L glass jar to sterilize in, for example). Or just add a recipe for “makeshift pouches”.
