You map is fantastic, but unfortunately there's a fairly major problem. With the new textures in Assassin Edition your custom textures have been knocked along the index. This means that in place of your custom textures are the new ones. This has happened to me and it's incredibly annoying. I wish textures were set by their path instead of an index number.
Luckily it's fairly easy to correct this.
Open data/default_map_settings.cfg and copy all of the textures to be loaded apart from those which were introduced in the new version of Sauerbraten and paste them in your map config file above your custom textures.
Hopefully the textures should be back to normal.
I has trouble explaining this very articulately, so I'm sorry if I didn't make any sense.
*edit*
I fixed the texture problem myself. Replace this as your config file and your map should be 'future proof'.
