The class state between the Browser and what is execute sometimes becomes desynchronized

[janehmueller]

Sometimes when editing code (in this case when changing the superclass of my class), the vm is executing code that was already removed in the browser. I get an exception/debugger that shows me method that I already deleted.
Things that don't fix this issue:

• Saving and opening the image again
• Saving the method again in the subclass (it should use the method of the superclass). Here the override also does not show the usual green arrow up
• Adding the methods the phantom class is calling (in this case an accessor). They are not found

Committing the classes via git, deleting them and then checking the commit out (and thus re-adding the classes) fixed the issue
