Then it wasn't you. I think
@FC1(SW) Retired was merging epubs because the sheer number in the serialized from one author was huge and was massively confusing; So one of the covers was edited to remove the numerical ID and have as a blanket cover for the series; Then look closely and you see the legs are wobbly and you can see where it was copy/pasted. A little annoying but nothing game breaking. Figured i would go back and fix those at some point. I am not artistically inclined, but i'm getting better with just fixing things.
Yeah get used to tools and how they act, and you can work with them. Just wish some tools wouldn't decide it knows what's best and change things around.
Regardless I'll help how i can when it's relevant.
