Since the Personal Story occurs prior to LS 1, the episodes that take place in Lion’s Arch should be set in the original, undestroyed version of it. And the same applies to any other zone that has changed (or will change) over time.
Is this possible? Will we ever see this? Otherwise, re-playing LS episodes in zones which are very different tends to make the story nonsensical.
PS episodes in LA are faintly ridiculous because, for example, people are discussing how Lion’s Arch will never fall when it is already destroyed all around them.
