This should be solved by SQ, it is just a unique side.

I'm running 3.1.0.0 and it doesn't find it either. Just for completeness I assume you mean the one that requires r9c3=6 to avoid the UR. So either the UR detection is slightly defective or the hierarchy of techniques is not being followed rigidly.
I have 81 brain cells left, I think.

That is what I meant and it does force r9c3 to 6.
