Hey fester, small word of advice from "the zen of mapmaking".
- Never update maps.
They are representative of a particular time and place/needs and desire of design. You are better off making new ones from scratch instead of trying to rekindle old flames.
In AH, due to the effort required to make some maps, it may seem unfeasable to do it, but its the only way to keep art fresh and clean (never second guess and release only when 100% happy).
I am hoping to start working on a map with stigler and I hope we have as much success as you have had! :-)
