In the book 1 directions for the 2020 Diagon Alley set (see pp. 43ff), I've run into the following issue:
In building the back of Ollivander's shop, we seem to be building some type of shelving unit:
Notice that the pieces just added stick out from the back a bit.
But later, the directions state to place the back of this shelving unit flush with an already-built wall:
This isn't confusion regarding perspective; later we see that we are to connect this shelving unit with the wall:
But how are we supposed to make this shelving unit flush with the wall if there are parts that stick out of the back of the shelving unit? Note that the wall is a single solid piece with no holes for these parts to stick into.
I've considered moving Ollivander's desk so that I can move this shelving unit forward (to the left), but this then prevents connecting the structural beam from the staircase to the wall (see step 108 in the directions; my image is too large to share). Moving his desk also prevents the staircase from rotating into the shop.
Am I missing something, or is this indeed an error? If it is an error, how have others solved this issue?
Note that we can't just move those pieces in the shelving unit so that they don't stick out; doing so prevents us from building the shelving unit, because the nubs on top of those "sticking-out" bricks gets in the way of the shelves snapping into place. Neither can be omit these pieces and slide them in later, because the nub from the pieces beneath them get in the way.
