yes i agreeI was going to ask the same thing.
Is it intentional that to get the achievment wer'e supposed to visit maps that you can only access once, during story, or character creation?
Common sense is that you'll have to visit character specific maps, but not maps that get closed off after you visit.
A good example would be "Black Heaven Main Computer" Room in the Scrapyard region.
The only way to access the map is to have a character visit it during a one-time quest in a story. I could complete the quest until I had a new character reach level 200 and only then I could start the quest.
also, I don't have enough slots for character in theserver I'm playing, so if I have to make a new character to get an achievment, I have to either delete a character, or play in another world.
