Now I'll mention the issues that I've faced so far:

1st issue:

The piece 17, the largest stair, is missing the lowermost step, but it was easy to fix, I just opened the page where piece 17 was in Photoshop, and I just made an copy of a part of the own stair's topmost step, making sure that I only cutted the needed amount of the step's texture. I used the height of the to guide myself for the cut process and since the other piece where the stair would be glued were also on the same page, it was way easier to predict the size I needed to cut. I got the measure of 11mm on the other piece where the stair should be glued by looking on the gluing spots on the lower part of the piece, and it worked very well after printing the fixed piece and building as shown on the photo.
