#5289 closed defect (fixed)

RemoveUnusedPrimitives: WARNING: Edges 14315 and 1937 joined by node 10801 could not be healed: Healing of edges 14315 and 1937 was reported to remove node 1661 while we expected 10801 instead

Description

The RemoveUnusedPrimitives function sometimes raises this confusing warning about expecting removal of a node and obtaining removal of another node. The warning is misleading because the expectance is wrong. When healing two edges which are connected on both sides on nodes having no other edge connected to them it is not predictable which node will be removed. The code should not assume it can predict that.

Another reason why the message is misleading: the edges are actually healed…
