Check your brick walls. They're all different now.

Yes I had this regret as well. I was using small batches of these, with a Training Wall in front for a door, as "placeholders" for premium buildings that are known businesses on the square, because of their flat tops.

I swapped them for CoC castle walls. Workable, but not as good as the other walls.

There was no improvement by doing this. They need to reverse it.
