Here's a few:
- Add 6 vertices, add triangles between the 4 first points, then the 4 last points (using very fast mode). Hit undo. It's now impossible to redraw triangles between the last 4 points.
- Probably related: Add 6 vertices, add triangles between the 4 first points, then the 4 last points (using very fast mode). Hit undo twice. Here you can add again triangles, using any method. Remove again the triangles using undo. At some point you'll get a crash.
- When 4 points are not in a convex configuration, there are several possible triangulations. LPC choses one according to vertices order (? - or vertices selection order?). This can result in many different triangluations, including overlapped wrong one (attached 4points_concave.lpc.txt)
- When 3 points among 4 are almost aligned, it would be great if LPC choosed the best triangulation (attached almostflat.lpc.txt)
