Just wanted to give some feedback:
Sapping Technique appears to only apply the first time you go to the jobs, and it stops working every time after (which kind-of softlocks the game, you don't have any way to make faster ichor and have to idle it with the passive gain).
Cybernetic upgrades to ichor gain also awkwardly require the sapping technique, so buying them out of the intended order might also cause glitches.
