Monster spawn again after die

[ApeCake]

I am not sure about the monster - you could maybe edit it's setting in the Model Editor and perhaps change it so it doesn't despawn when you are dead? And about the .lang you have there, try adding <RESOURCES></RESOURCES>.

Don't put anything between the RESOURCES, just put it in the .lang, but make sure you paste it inside <LANGUAGE> </LANGUAGE>. Or try this;
<CATEGORY Name="CustomStoryMain">
<Entry Name="Description">My Description.</Entry>
</CATEGORY>
put that there INSTEAD of
<CATEGORY Name="My map">
<Entry Name="Description">My description</Entry>
</CATEGORY>

I think this is the problem. Hopefully that works.
Viel Glück und Spaß!
