I keep getting that error when hot-reloaded after I added a custom c++ scene component to my actor blueprint. It resets all the settings for that component. Is there any way around it?

I think it’s related to this [Unreal Engine Issues and Bug Tracker (UE-64076)](https://issues.unrealengine.com/issue/UE-64076) and [Unreal Engine Issues and Bug Tracker (UE-35870)](https://issues.unrealengine.com/issue/UE-35870) bug and maybe perhaps this [Unreal Engine Issues and Bug Tracker (UE-52220)](https://issues.unrealengine.com/issue/UE-52220)

Here is a better temporary workaround that fixes the bug temporarily.

- Delete the following folders from your project:  
.vs  
Binaries  
Intermediate  
Saved  
\*.sln

- Then right-click the .uproject and select “Generate Visual Studio project files”.

- Open the \*.uproject and let it generate and build all the editor files again.

- Compile and redo lighting.
