Repeating some notes from the website.
Cannot emphasize this enough.
When you start editing files remember to rename them first so you don't change your original stock scenarios, oob and pdt files.
If you want to create your own scenario you will want to create your new pdt file, pick or create an oob file and choose a map.
If you create or modify an oob file the most common problems come from the Begin-End matches. These will cause the scenario to fail to load properly.
Once you rename the scenario you can change the pdt file it uses as explained in the page on the Ediitor.
Be aware that any changes you make will affect the balance of the scenarios. Even the use of Optional Rules can tip a scenario from balanced to favoring one side or the other.
