Dear Developers,

I found extrude may have some bug. To reproduce the bug

1. Prepare a square sketch,
2. create circular pattern of quantity 3. 
3. extrude whole sketch about 20mm
4. go back to sketch, double click the circular pattern symbol, and change quantity to 5
5. we got error shape!!!

I show each step figure as attached.

best regards
