i used the script placer.Just wondering, did you use the newest version? (wich includes the prefabs, xmodels, ...) Did you place the script placer and it's components in your WaW ROOT directory? I'll check if it works myself, thought I tested all features after the bugfixes. :s
Edit: Just tested it, working perfectly fine. What options did you check in the script placer?
Edit 2: Updated the Script Placer to v0.19.1.1, changelog is in the first post.
