When using the tutorial system inside UE4 (I am creating a tutorial for a marketplace submission) I get frequent crashes when adding new stages to the tutorial.
I also experience frequent crashes when trying to select a widget anchor.
Hitting the compile button often helps, but changing a single option, then hitting compile, then making the next change isn’t a very fast workflow.
