This is probably a problem with the script. Whenever I've seen this, it's been from one of two causes:
1) The script isn't capable of finishing itself because it hasn't been properly ended. This probably isn't the case with EB. :)
2) The script hasn't been fully started.

My recommendation? Delete your map.rwm file (I do this compulsively) and start a new game from scratch. Make sure you click the show-me, then make sure it runs properly. I think we can assume the script is properly written, so it's got to be something in the initiation.
