Would it be possible to have Hot Reload in Blueprint. What i would like to see is…We Press Play → Eject the player → Open up the Player Blueprint → Make changes (just the defaults. I dont think node editing will be possible) → Press compile → Possess the player and TA-DA!! The changes applied!
Thanks for your report! Changing the Blueprint defaults should auto-propagate BUT this causes a PostEditChange which currently breaks certain classes like Vehicles (should work fine for normal Pawns). In the future we may look at adding the ability to edit the Blueprint node graph on the fly.
