[Game of Thrones - Season 8 spoilers]The trenches disappeared in the latest episode. What happened to the trenches?

Outside of Winterfell, a giant trench was dug to aid in the battle.  In the latest episode, during the funeral pyres, we can see Winterfell at a distance such that, the trench should be visible.  It is gone.

Did it disappear?  Did they fill it in?  If so, how and why?  Where did they even get the manpower for that?  Also, where are the literal army of corpses from the others?  There should be a hundred thousand corpses or more, how did they manage to move them all so quickly, a task that should take weeks with the limited manpower available?

A (Plot)Hole filling company came in and fixed it up for them, and in record time too. After that they had to hurry on to King's Landing to build what looks like a barren, flat wasteland in what was previously a lush peninsula surrounded by the sea on all sides.

Ah the beauties of capitalism.
