Found this problem when I comment the initialized code in construction function and forget to comment related code in Tick(). When I tried to compile in editor the editor crash.
Can you paste the code? I might move this to bug raport if it’s worth it. Keep in mind that hot reload is not perfect and us much it will be improved there always be some collisions with working engine code which will cause unexpected behaviors and crashes, it’s like replacing game cartridge while game is running, sometimes you simply need to restart editor.
