Builder's Buddy Script error..

I have been using the Builder's Buddy packaging scripts for several months and it has worked perfectly. However, my last 2 builds which have been less than 5 objects/prims each, have been getting script errors when customers rez them. I have witnessed this. There is a little script icon above the rez box after the build has finished rezzing. They have rezzed it on their own land. The builds seem to rez correctly but I'd prefer not to have script errors. Has anyone else had this happen or know what the fix is? Is there a new version of Builder's Buddy?
