Editor now provides error message stating "Cannot add components that have "Within" markup" rather than crash
Crash occurs when attempting to add an actor component c++ class to a game mode blueprint if the actor component is tagged with the Within="GameMode".
Found in 4.11.2 binary, reproduced in 4.10.4 binary.
Regression?
No, reproduced in 4.10.4 as well.
1. Open the editor
2. Create a new actor component C++ class
3. In the UCLASS() macro, add this line "Within=(GameMode), with GameMode being the name of your game mode class.
4. Compile
5. In the editor, create a blueprint based on your game mode
6. Open the game mode blueprint
7. Attempt to add your actor component C++ class to the game mode blueprint
Result: Editor crashes
Expected: No crash would occur and actor component would be added successfully.
