How does steady hand + basic synth = failure?

[BlaiseArath]

Could it have worn off? Or are you using Basic Touch sometimes by mistake? I mean, Basic Touch (Quality/HQ Rate) only has 70%, so with Steady Hand its 90%, and can fail. Basic Synth is what you mention but that is 90% and should be 110% with Steady hand, and from my rather extensive experience, does not fail.

I think I'm going to have to go with Human Error here, I've never had this happen and I'm about 3 crafts deep into 50, with the other 5 soon following.

But you have

Basic Touch - 70% Success - Increases Quality

Basic Synth - 90% Success - Increases Progress.
