Talk:Linkability Rules

Although the initial failure mode of unlinkable sets is correct in principle. It doesn't take the fact into account the checking algorithm is 'global coordinate/position based', while linked sets can be rotated over general angles. A new linkability check over a valid linkable set, which is rotated (causing a different order in the prim selection of the linkability check) can cause this set to become invalid.

Linkability checks over already linked sets should be performed using the coordinate system as established by the rotation of the linked set, instead of a global coordinate system, to prevent a rotation of a valid linked set breaking the linked set. [DamaniosThetan]
