What is the logical reason behind this? (or is it possible and I don't know?)
In below illustration I can knit any 2 surfaces together. But when i try to knit all 3 surfaces together or 2 surfaces at once and then knitted surface with the third surface it throws error. All the three surfaces share a common edge.
Practical application is when I try to knit the 'tent-like' surface on top of base surface the error appears (there surfaces - split face, base surface and tent-like surface have a common edge). But I can knit if i delete the split surface before making the tent-like surface.
