Here's the script. Maybe it only works in the Heroes 5 editor, but I'm using the Tribes of the East editor?
There are several possible reasons. The best way to debug is to use the console. I personally had problems once because of an incorrect encoding of the .txt file (this is relevant if you printed it using Notepad instead of an editor; in that case, you need to consider that the game requires Unicode). Also, I'm not sure if "Maps/SingleMissions/Town/Deadst.txt" will work. It's better to write it like this: "/Maps/SingleMissions/Town/Deadst.txt", and even better: GetMapDataPath().."Deadst.txt".
