How rare are Implant Circuitry Mk. III components?
I seem to have progressed far enough into the game where Implant Circuitry Mk. IV is dropping. It's possible my game is bugged, but the Deck13 support site doesn't currently list this as a bug. An improvement of the sequel over the original Surge is that higher marks of components can be downgraded to a mark lower, so my Mk. IV circuitry was able to craft the Mk. III heal injection, and also upgrade to Mk. IV.
