I keep seeing <INVALID OREF>zMypropertyGetSwizzled+3^myClass.2 in the error log. In my case, Myproperty is a property of myClass. And Myproperty points to the the object of other class in the system. This error happens to 2 properties in the same class, and they are both object properties. This error pops up occasionally, and make the debugging harder.
Anyone knows what the issues are?
