I don't get this cant find the files
"Testing the map
Exit the editor and save the changes. (The changes will be applied to the map you edited. You may need to go and rename the file or copy, paste, rename in your module folder.)
You need to then edit, module_scenes,module_scripts and module_strings and add your map in. If you do a search for multi_scene you'll find the relevant area for your code. Looking at other maps should make it self explanatory. You may need to copy in the height map code of the map you edited. This is the 0x09808088 number that appears in module_scenes.
After you've done that, voila, start up a server, choose siege and load up your map!"
