The funny thing is, that even original f2 maps have a lot of those "mapping mistakes". There also is at least one tile that is missing in general, so unless some other server made it that's all we've got.
You have to be a mapper to even notice those issues though, anyway. I also thing that the izer gives aop maps their typical look without striking anyone as repetitive. Fixing the izer's results manually is wasted effort, in my opinion, though it can help to quickly ize a map a couple of times and then pick the one that looks best.
