Hey,
The project can be donwloaded from: http://elderson.net/BugReport01.zip (27mb).
If you open the project and select “Actor” in the world outliner, you will see a red line going from the actor to x + 100. If you then open the blueprint “B_TestSceneComponent” under Content, and select the variable “Test” and change the default value. You can then recompile the blueprint, after compiling (saving doesn’t matter), the red line is not there anymore.
Any change to the blueprint that cause it to be marked modified, so you can recompile it will cause this. I’ve implemented a “trigger” boolean value on the TestSceneComponent, when changed (thru PostEditChangeProperty) will register the component again with “this->RegisterComponent();”. That will cause the Visualizer to start working again.
Cheers,
Alex
