tbh, at first thought i didn’t understand how i should avoid overlapping vertices, but when i saw your solution, it was perfectly clear. I had a wedge on my own, but yes, i stepped into the “trap” of moving the entire face 2m +y and then simply lowering the upper edge down to the lower one - which made the 2 corner vertices overlap with their counterparts.
it’s important to avoid things like that - learned something in this lession - thank you!
