Poly Modeller & Renderer?

I said a few days ago "What is and when exactly does this pink dots appear in modo, I have been working in modo for quite awhile now and I haven't noticed it?"

Now I have seen it!, damn what a heck is this? pink dots? they seem to happen only when exporting from Moi as a .lwo

Is there any solution to avoid these, are they bad vertices...?
