4.7p3 Crash bug when editing array properties
This one I can actually tell you how to reproduce! \o/ 4.7 preview 3 link text
Create a new dummy project that's based on the normal Vehicle template.
Create a new BP called GarageBlueprint based on Actor to hold our cars. Add a public member variable called cars and make it into an array of sedans.
Drag the GarageBlueprint into the map. Drag a few Sedans into the map. Select the garage and pull up it's property panel. Use + on the garage's cars array and add an element for each sedan and assign them each to a diff one.
In the GarageBlueprint, add some code into the constructor. I've attached what I did.
Go back to the properties panel for the garage in your map. When you compiled this, the sedans were all cleared out of the cars array, but the elements are all still there saying None.
Now try any interaction with the cars array, assign an element, insert a new one, add one, duplicate etc, anything you touch after that seems to make it crash.
I am going to mark this as answered for tracking purposes. I have entered a bug report for your crashes, as reported here:
I believe that your specific crashes are all being pulled from the same general error, which appears consistently throughout your crash logs. If you run into any more crashes please don't hesitate to upload them so we can try to get to the root of what is occurring. Thank you!
