I think I get it? When you bend a quad like that, it needs to be turned into two triangles, and it kinda guesses which two verts to connect. You can try connecting the other two verts to fix it. (Assuming I understand correctly. I also don't use bb much, so I hope this helps.)

I'm not sure I understand the question?

love this one, good taste

:D I hope it's an extended version of Working Late, I just found your stuff today and that song makes me unreasonably happy. Looking forward to whatever it is regardless!
