1. Create two actor blueprints (ActorA, ActorB)
2. Add a child actor component to ActorA. Set the child actor class to ActorB.
3. Add a variable to ActorB of type ActorA.
4. Compile, save, and restart the editor.
5. Attempt to open either blueprint. This results in an editor crash.

Hey mattypoo,

This is actually the same crash I just reported a few minutes ago, but with a slightly different repro. Here is a link to the tracker so you can keep an eye on the issue’s status: [Unreal Engine Issues and Bug Tracker (UE-39323)](https://issues.unrealengine.com/issue/UE-39323)

I’ve updated the ticket with your repro as well.

Thanks for your report.

Have a great day!
