I am totally new to blender, so please forgive me if it is a dumb question.
When I add a face by pressing 'F', I found out it adds an vertices to where it seems to be middle position of selected points.
It doesn't show up in vertex select mode, but I can see it on Face select mode. Because it doesn't show up in vertex select mode, I tried to delete it but I can't.
and it mess up subdivision surface.
I am so confused why it is happening, please help. Thank you!
end up with weird shape because of that dot. :(
