It seems that kinetic augments cannot shear sheep, this means that it is impossible to automate sheep shearing, as shears are not a valid turtle upgrade.

You should be able to call turtle.place with the shears. We even have a test for it!

That said, this probably still is a bug - I'd definitely expect it to work!

this might be another case where the raytrace in kinetic augments is failing

I do recommend calling turtle.place with the shears in the future!
