Hello there,

I am currently encounter a extrude bug that I have a hard time to describe. I have a insect leg that is made out through create polygon tool then append to polygon tool, but when I try to extrude through selecting all faces, it did not have the original faces and appear many different faces from the edge I have created.

Here is the link of picture that I have the issue with the extrude tool:

I am wondering if there is any way I can fix it since I do not want to use the append to polygon tool to fill each of them back in future as it will take lots of time.
