IsValidLowLevelFast error

Exception caught at this line in file UObjectBase:

if (Class == NULL || Class->ClassDefaultObject == NULL || ((UPTRINT)Class->ClassDefaultObject & AlignmentCheck) != 0)

I just used IsValidLowLevelFast to check actor’s validity

Hey -

Can you post the code that you’re using to trigger this exception? Are you running your project directly or through Visual Studio debugger? If you are running through VS can you let me know if you hit the same exception/crash? Also post callstacks and log files if this is the case. Any additional information you can provide to help me reproduce this will help narrow down what exactly is causing it and how to fix it.
