In v3.x, the class GsNMethod replaced GsMethod, and after upgrade from 2.4.x to 3.x, all methods must be recompiled before they can be executed.
If there are any unrecompiled instances of GsMethods on current versions of classes in the user's SymbolDictionaries, ClassOrganizer >> referencesToObject: encounters a message not understood error on #_literalsIncludesValue:.
This affects GBS, in which functions to find all references invoke the ClassOrganizer functionality.
Ensure that you recompile methods for all visible classes.
