Did anybody have trouble getting this damn achievement?

Yes, my brother even has every other achievement but that one his score is 980/1000

Yes, very diffucult achivment to get

I had no luck with it whatsoever, mainly because I could not find the last seed... I even re-visited every listed location but no such luck... it's really unfortunately because that one stinking ability cost me a ton of gamerscore...

I was a seed short and sure that was all I was missing but I finally found it and nothing so now I'm playing through again with a guide.

Yeah i had a lot of trouble with this one but i finally managed to get it. I was missing like 2 seeds under the sea.

I'm stuck at 980/1000 partly because I can't be bothered to find everything yet!

I do have a question for those that got it though. I know that items you miss end up in the auction house, but what about money treasure? You can't buy money at the auction house, but I read that it counts towards the achivement, so if I miss it, it's gone?
