[BUG] Infinite loop inside blueprint


When writing an infinite loop (while for example ) inside blueprint and run it, it’ll just exit the play mode without any warning or error log !

I believe it’d be worse in other complicated scenarios.


Can you check your Output Log, are you not seeing a message like the one below when you exit PIE?

There should be a message in your log that states a Runaway loop was detected. We have an issue in our database for tracking and review by our developers that a pop-up message rather than the output log, might help illustrate that an infinite loop was detected and that’s why you were kicked out of PIE.
