I have been facing this issue after updating to 4.17.2.
Unreal editor crashes when i try to add an instance inside level editor.
Editor also crashes,when i try to duplicate a c++ actor class with HISM component,in level editor by ALT dragging it.
HISM component should have some instance for this crash to happen.
Is this related to UE-50348 ?
Because,it is giving me same error as mentioned there.
Steps to reproduce the crash in bp:
- Create an actor blueprint.
- Place it in level and add a HISM component.
- Select the mesh and add an instance.
Steps to reproduce the crash while duplicating in editor:
- Create an actor c++ class and add a scene component and make it as root component.
- Add a HISM component and add some instance.
- Create a blueprint from this class and place it in level
- ALT drag it to duplicate it.This is where crash happens.
I am sharing a link to my test project.
Thank you.
