Well, basically, it is not possible to fix this problem with the current logic, where each facet is an independant body. We need to consider a triangulated surface as one entity and define contacts differently if they are on facets, edges, or vertices. In order to do that, we need a well designed data structure defining the connectivity of facets, and used by Ig functors to track the contacts passing from one facet to the other.
The problem is similar as in chained cylinder, but in 2D (while chained cylinders are 1D). It would be a big step, but it is not a small job.
