Hey there I had some luck in getting around that glitch. Might not work but give it a try
For the piece under the jar you want to position yourself by clicking the jar and then clicking like hell. That actually helped me out try to match up with the arrow that pops when it tries to autopath you to the blueprint piece.
Same concept with the full blueprint getting close to the target for the autopath spot and clicking like hell got me past it.
I hope it works for you if you happen to try it.
