Thanks for the report. I believe this would be considered a known issue. I'm guessing it just uses half of the model when using symmetry in this case, which means the algorithm wouldn't know there's another side to stitch to.

@Sebastian Parborg (zeddb) Would probably know for sure though.

@Hans Goudey (HooglyBoogly) this is exactly the case.
I've looked into this previously but it is not an easy fix.

That's what I figured. Known issue then!
