UndefinedObject(Object)>>doesNotUnderstand: #methodClass RGMethodDefinition>>asMCMethodDefinitionFromActiveDefinition

This happened to me again in a different image, but this time with a different cause. I removed some methods via Calypso and somehow the PackageSet got out of sync and still listed the non-existent methods. The workaround to be able to keep working was to click back to `#basicSnapshot` in the debugger call chain, "debug it" on `rPackageSet methods`, and then manually re-evaluate the lazy initialization block. ----- Cheers, Sean -- Sent from: http://forum.world.st/Pharo-Smalltalk-Developers-f1294837.html
