Hi, I am new in Houdini and I have big problem. I have a model of gunhip and when I add a edgeloop ( to have nice subdivision ) Houdini just freeze ( not exactly freeze, I can save it with Ctrl + S but I cant click on anything ). It doing it on Linux and too on Windows, is it a bug ? In attachment are 2 clay renders of basic-mesh.

*it not freeze every time, but in 5 times of 10 it does.

Thanks for help.
