[Bug] Changing parent class causes crash on world load

Development Programming & Scripting C++

We have a heirarchy of classes (LootBase, Lootitem, FoodItem, TomatoSoupFoodItem style)
[ all blueprints, no C++ ]
In the constructon script of all blueprints we have a call to the parent constructon script.

We have lots of loot in the world.
I then changed the parent class (LootBase) to have 2 more integer variables.

After that every time we load the world tile with the loot, UE4 crashes (either on load in editor, or on level load)

If I go into the blueprints and Refresh Nodes on the Parent: Construction Scrip node that fixes it.

It is very tedious to go through all our loot items and fix them every time there is a change.

Also deleting the call to the parnet creator fixes the error message.

Now that all the error messagesa are gone, it still crashes.

I tried deleting Intermediat and Binaries folders too. That did not fix it.

Is there a better solution?
Is this a known bug?

Hi SND R Keene,

I attempted to reproduce this in-house but I couldn’t get your results. I’m sure that my setup is much more simplistic than your game. Could you try reproducing this in a new test project and provide some screenshots or the test project itself?
