Map updating removes description!

Hello there.

I've noticed this problem quite a bunch of times, and i think i should report it now. When updating maps in the map section (and only in the map section!) it sometimes 'looses' the description. Then after i've updated it just says "No description". It doesnt happen everytime i update, but happens. And its really anoyying to start over making a new map description. I dont know if im the only one that have experienced this, but now you guys have a chance to fix it ;)
