Creating a large polygon that caused a jump to new area (white). While deleting points the error happened.

Picture of error uploads but does not display.
<font color="red">Edit by the moderator: The picture is the following one. I do not know why the forum is not displaying photos (have to dedicate some time to investigate the reason). I also do not know why the error happened. It looks like you pressed the delete key and many points were selected. One (or more) of these points had an index that exceeded the maxinum number of points that the polygon had. Thank you for reporting errors. They will be extremely useful when revising SBX.</font id="red">
