Mojang, you can remove this post, I found a solution to my problem, i'll use the "Fill and Replace" tool in MCEdit to replace the missing blocks

Kumasasa, I have trouble loading my version of the map, the original one seems to work fine.

Daniel Mas, I think you didn't understand me right. I only used bukkit to build the map. I copied the world save from the bukkit server and opened it with a clean unmodded Minecraft 1.7.9 version, and the world was loaded without any problems. I even copied the world with MCEdit to another world, I thought that bukkit was making some issues, but there is something not right with this snapshots. I don't know if this will help, but I downloaded the map from Planet Minecraft and I used VoxelSniper and WorldEdit when I was building the map.
Here's my world save: https://www.dropbox.com/s/i9j6zejs1hns09h/world_spawn.zip
Here's the map I downloaded: http://www.planetminecraft.com/project/capture-the-flag-map-1/
