Why don't they do that with all the piece's?

In the new AT-AT set (75440) I got 1x1 flat piece with the mold injection hole on the bottom site, (It's the first time i notice this) why don't they do that with all molds, they would almost always be hidden. It's especially frustrating with those "ingot" pieces. submitted by /u/AndriX3S [link] [comments]
