This is in Pharo 7 In a package I have a class that has methods that I can see in a browser. When I save it to an mcz file the class isn't saved in the file for the package. When I file out the class and file it back in there is a load error. The fileout has many of these errors scriptMarkerFor:withLabel:on: ** ERROR! THIS SCRIPT IS MISSING ** renderNameAndAddressFor:on: ** ERROR! THIS SCRIPT IS MISSING ** Those methods are defined in the image and in the class's super class. I cannot change the class's package because I get method dict lookup errors. Making a copy of the class fixes everything for the copied class. Is there a way to scan my package for other classes that are broken like this one was? Thanks Paul
